Quan Zhou 525c469e5d wifi: mt76: mt7921e: fix init command fail with enabled device 
For some cases as below, we may encounter the unpreditable chip stats
in driver probe()
* The system reboot flow do not work properly, such as kernel oops while
  rebooting, and then the driver do not go back to default status at
  this moment.
* Similar to the flow above. If the device was enabled in BIOS or UEFI,
  the system may switch to Linux without driver fully shutdown.

To avoid the problem, force push the device back to default in probe()
* mt7921e_mcu_fw_pmctrl() : return control privilege to chip side.
* mt7921_wfsys_reset()    : cleanup chip config before resource init.
