[GIT PULL] firmware: arm: Fixes for v7.4

[Sudeep Holla]

Hi ARM SoC Team,

Please pull !

I have included one dts file fix in this, hope that is OK. Let me know
if you prefer to keep DTS separate even for fixes.

Regards,
Sudeep

Arm Firmware Interfaces(SCMI/FF-A/SMCCC) fixes for v7.4

SCMI fixes correct protocol-device creation and request tracking in raw
mode, allow the generic and i.MX pinctrl drivers to share the standard
SCMI pinctrl device, and avoid creating unused performance-domain
devices that block cpufreq consumers through fw_devlink ownership. It
also includes dropping now unnecessary ACPI config guards and several
robustness fixes: bound i.MX MISC syslog and control responses,
unregister notification callbacks on event-enable failure, and free
mailbox state when shared-memory mapping fails.

The FF-A notifier fix distinguishes notification IDs within a hash
bucket, preventing callback registration and delivery from using a
colliding ID.

SMCCC and GICv3 fixes restore builds on 32-bit ARM when SMCCC discovery
is unavailable, while restricting the discovery dependency to arm64
where the NVIDIA erratum workaround applies.

Finally, correct the Corstone1000-A320 GIC redistributor region size
for its GICv4 configuration.
