crypto: qat - preserve ADF_GENERAL_SEC
The ADF_GENERAL_SEC configuration section contains values that must be
preserved during state transitions (down -> up, up -> down).
This patch modifies the logic in adf_dev_shutdown() to maintain all
key values within this section, rather than selectively saving and
restoring only the ADF_SERVICES_ENABLED attribute.
To achieve this, a new function has been introduced that deletes all
configuration sections except for the one specified by name.
This function is invoked during adf_dev_down(), with ADF_GENERAL_SEC
as the argument. Consequently, the adf_dev_shutdown_cache_cfg() function
has been removed as it is now redundant.
Additionally, this patch eliminates the cache_config parameter from
the adf_dev_down() function since ADF_GENERAL_SEC should always be
retained. This change does not cause any side effects because all
entries in the key-value store are cleared when a module is unloaded.
