MT7921 contains a microprocessor with which the host can use command/event to communicate to implement offload features such as establish connection, hardware scan and so on. The host has to download the ROM patch, RAM firmware and finally activate the MCU to complete the MT7921 initialization.

v2:
- Mark the patch as -next

v3:
- Remove sw scan support
- Get rid of dbdc code
- Run mt7921_configure_filter hodling mt76 mutex
- Correct Txp programming in Txd
- Correct fw log to host command
- Correct eeprom offset definition
- Update rate adaption info report
- Remove unused code and fields in struture
- Split the previous driver into several patches for easy review
