These are some dodgy "convenience" macros for the DRM driver to peek
into NVKM state. They're still used in a few places, but don't belong
in nvif/device.h in any case.
Move them to nouveau_drv.h, and modify callers to pass a nouveau_drm
instead of an nvif_device.
v2:
- use drm->nvkm pointer for nvxx_*() macros, removing some void*
v3:
- add some explanation of the nvxx_*() macros

There's no good reason the ioremap() that results from nvif_object_map()
should fail, so add a check that the map succeeded, and remove the rd/wr
methods from display channel objects.
As this was the last user of rd/wr methods, the nvif plumbing is removed
at the same time.

The next commit removes the nvif rd/wr methods from nvif_device, which
were probably a bad idea, and mostly intended as a fallback if ioremap()
failed (or wasn't available, as was the case in some tools I once used).
The nv04 KMS driver already mapped the device, because it's mostly been
kept alive on life-support for many years and still directly bashes PRI
a lot for modesetting.
Post-nv50, I tried pretty hard to keep PRI accesses out of the DRM code,
but there's still a few random places where we do, and those were using
the rd/wr paths prior to this commit.
This allocates and maps a new nvif_device (which will replace the usage
of nouveau_drm.master.device later on), and replicates this pointer to
all other possible users.
This will be cleaned up by the end of another patch series, after it's
been made safe to do so.

These were once used by used by userspace tools (with nvkm built as a
library), to access multiple GPUs from a single nvif_client.
The DRM code just uses the driver's default device, so remove the

This was once used by userspace tools (with nvkm built as a library), as
a way to select a "default device".
The DRM code doesn't need this at all as clients only have access to a
single device already, so inherit the value from its parent.

Currently we allocate all 3 levels of radix3 page tables using
nvkm_gsp_mem_ctor(), which uses dma_alloc_coherent() for allocating all of
the relevant memory. This can end up failing in scenarios where the system
has very high memory fragmentation, and we can't find enough contiguous
memory to allocate level 2 of the page table.
Currently, this can result in runtime PM issues on systems where memory
fragmentation is high - as we'll fail to allocate the page table for our
suspend/resume buffer:

Luckily, we don't actually need to allocate coherent memory for the page
table thanks to being able to pass the GPU a radix3 page table for
suspend/resume data. So, let's rewrite nvkm_gsp_radix3_sg() to use the sg
allocator for level 2. We continue using coherent allocations for lvl0 and
1, since they only take a single page.
V2:
* Don't forget to actually jump to the next scatterlist when we reach the
end of the scatterlist we're currently on when writing out the page table
for level 2

Add the NVreg_RegistryDwords command line parameter, which allows
specifying additional registry keys to be sent to GSP-RM. This
allows additional configuration, debugging, and experimentation
with GSP-RM, which uses these keys to alter its behavior.
Note that these keys are passed as-is to GSP-RM, and Nouveau does
not parse them. This is in contrast to the Nvidia driver, which may
parse some of the keys to configure some functionality in concert with
GSP-RM. Therefore, any keys which also require action by the driver
may not function correctly when passed by Nouveau. Caveat emptor.
The name and format of NVreg_RegistryDwords is the same as used by
the Nvidia driver, to maintain compatibility.

Nouveau manages GSP-RM DMA buffers with nvkm_gsp_mem objects. Several of
these buffers are never dealloced. Some of them can be deallocated
right after GSP-RM is initialized, but the rest need to stay until the
driver unloads.
Also futher bullet-proof these objects by poisoning the buffer and
clearing the nvkm_gsp_mem object when it is deallocated. Poisoning
the buffer should trigger an error (or crash) from GSP-RM if it tries
to access the buffer after we've deallocated it, because we were wrong
about when it is safe to deallocate.
Finally, change the mem->size field to a size_t because that's the same
type that dma_alloc_coherent expects.

__counted_by
Fake flexible arrays (zero-length and one-element arrays) are deprecated,
and should be replaced by flexible-array members. So, replace
zero-length array with a flexible-array member in `struct
PACKED_REGISTRY_TABLE`.
Also annotate array `entries` with `__counted_by()` to prepare for the
coming implementation by GCC and Clang of the `__counted_by` attribute.
Flexible array members annotated with `__counted_by` can have their
accesses bounds-checked at run-time via `CONFIG_UBSAN_BOUNDS` (for array
indexing) and `CONFIG_FORTIFY_SOURCE` (for strcpy/memcpy-family functions).
This fixes multiple -Warray-bounds warnings:

This moves the initial effort to the latest 535 firmware.
The gsp msg structs have changed, and the message passing also.
The wpr also seems to have some struct changes.
This version of the firmware will be what we are stuck on for a while,
until we can refactor the driver and work out a better path forward.

This commit adds the initial code needed to boot the GSP-RM firmware
provided by NVIDIA, bringing with it the beginnings of Ada support.
Until it's had more testing and time to bake, support is disabled by
default (except on Ada). GSP-RM usage can be enabled by passing the
"config=NvGspRm=1" module option.
