wifi: mt76: mt7921e: add pci .shutdown() support
Some combinations of hosts cannnot detect mt7921e after reboot. The interoperability issue is caused by the status mismatch between host and chip fw. In such cases, the driver should stop chip activities and reset chip to default state before reboot.
