From: Chia-Yuan Li <leo.li@xxxxxxxxxxx>
After firmware boots, it reads keys info from efuse and checks secure
checksum, but suddenly failed to access efuse resulting in probe failure,
and driver throws messages:
rtw89_8852be 0000:03:00.0: fw security fail
rtw89_8852be 0000:03:00.0: download firmware fail
rtw89_8852be 0000:03:00.0: [ERR]fwdl 0x1E0 = 0xe2
rtw89_8852be 0000:03:00.0: [ERR]fwdl 0x83F0 = 0x210090
Retry five times to resolve rare abnormal hardware state.
