From: Zong-Zhe Yang <kevin_yang@xxxxxxxxxxx>
RTL8922A FW supports CRASH_TRIGGER feature from v0.34.30.0.
After it, debugfs fw_crash can accept type 1 on RTL8922A to
trigger firmware crash and verify L2 recovery.
Besides, RTL8922A sync address offset of reserved payload engine.
And, SER (system error recovery) tweaks conversion from WCPU address
to indirect access address for RTL8922A. The new conversion works
for all supported chips.
