wifi: rtw89: support SER L1 simulation
SER (system error recovery) can deal with different crash types by
different levels of processes. Previous FW crash simulation triggers
a CPU exception which is one kind of SER L2 type. It can verify SER L2
flow which includes HW/FW restart.
Now, we want to increase crash simulation types. A debug function is added
to trigger control error in purpose for SER L1 simulation/verification.
And, debugfs fw_crash is extended to accept different parameters.
echo 1 > fw_crash:
simulate CPU exception as before
(keep 1 for compatibility with previous)
It will be catched and handled by SER L2.
(this requires HW/FW restart)
echo 2 > fw_crash:
simulate control error
It will be catched and handled by SER L1.
(driver and FW cooperate to recover this)
Besides, in order to apply to the above two cases,
rename RTW89_FLAG_RESTART_TRIGGER to RTW89_FLAG_CRASH_SIMULATING
and adjust where SER flow clears this bit for both L1 and L2.
