Merge tag 'pull-target-arm-20231027' of https://git-us.linaro.org/people/pmaydell/qemu-arm into staging

target-arm queue:
 * Correct minor errors in Cortex-A710 definition
 * Implement Neoverse N2 CPU model
 * Refactor feature test functions out into separate header
 * Fix syndrome for FGT traps on ERET
 * Remove 'hw/arm/boot.h' includes from various header files
 * pxa2xx: Refactoring/cleanup
 * Avoid using 'first_cpu' when first ARM CPU is reachable
 * misc/led: LED state is set opposite of what is expected
 * hw/net/cadence_gen: clean up to use FIELD macros
 * hw/net/cadence_gem: perform PHY access on write only
 * hw/net/cadence_gem: enforce 32 bits variable size for CRC
