rtw89: support FW crash simulation
Originally, there is already a mechanism, SER (system error recover),
to deal with HW/FW recovery. After FW v0.13.36.0, FW supports a H2C
(host to chip) command to make a CPU exception. Then, SER is supposed
to catch this FW crash and do L2 reset. This feature is a simulation
to verify if flow of recovering from FW crash works.
Usage of fw_crash debugfs is as the following.
$ echo 1 > fw_crash // trigger FW crash and wait SER handling
$ cat fw_crash // return 0 if restart has been done
