[PATCH v3 02/10] wifi: mt76: connac: add support for dsp firmware download

From: Peter Chiu <chui-hao.chiu at mediatek.com>
Add FW_START_WORKING_PDA_DSP for the indication of starting DSP
firmware download, which is for phy-related control.
The firmware is transparent to the driver, but it's necessary for the
firmware download process.

v2:
- merge two commits
- move main load ram code to a regular function
v3:
- remove all macros to directly call __mt7996_load_ram()
- add back missing code which records fw_version to wiphy
