Bug Description
[Impact]
The new firmware for QCA9377 supports Qualcomm's RED(Radio Equipment Directive) compliance and requires more IRAM banks. The origin 4 banks doesn't fit the new BDF and firmware.
[Fix]
Change the bank number from 4 to 9.
[Regression Potential]
Low, increasing the number of IRAM banks should be no harm.
[Misc]
Currently, both driver patch and new firmware do not upstream yet. For the sake of avoiding dkms package, we can change t
he IRAM bank number before their patch is ready.
