Subject: [PATCH v5 01/11] wifi: rtw88: print firmware type in info message

It's confusing to read two different firmware versions in the syslog
for the same device:

rtw_8822cu 2-1:1.2: Firmware version 9.9.4, H2C version 15
rtw_8822cu 2-1:1.2: Firmware version 9.9.11, H2C version 15

Print the firmware type in this message to make clear these are really
two different firmwares for different purposes:

rtw_8822cu 1-1.4:1.2: WOW Firmware version 9.9.4, H2C version 15
rtw_8822cu 1-1.4:1.2: Firmware version 9.9.11, H2C version 15
