[0/3] wifi: rtw89: improve firmware code to be backward compatible with old driver

Patch 1/3 and 2/3 are to refine code related to firmware. Among them,
patch 2/3 is to use schedule_work() to load firmware, so it will be
simpler to load more firmware and files in the future. The upcoming files
include predefined format string of firmware log, another MCU firmware
of WiFi 7 chip, and so on. I will explain them when we submit the patch.

Patch 3/3 is to be backward compatible with old driver. Currently, only
8852b support firmware-1.bin, and other can support more, like
firmware-2.bin and firmware-3.bin.

Supported matrix is listed below:
                    dirver-0    driver-1    driver-2
 firmware.bin          O           o           o
 firmware-1.bin        x           O           o
 firmware-2.bin        x           x           O

 Big-O: MODULE_FIRMWARE()
 small-o: supported firmware
 x: driver doesn't try to load

This patchset is based on two other patchsets:
 - "[PATCH v2] wifi: rtw89: add counters of register-based H2C/C2H"
 - "[PATCH v4 0/5] wifi: rtw89: preparation of multiple interface concurrency support"
