    wifi: rtw89: 8852b: try to use NORMAL_CE type firmware first

    New firmware type NORMAL_CE is introduced to support P2P-PS and hardware
    scan, but no LPS-PG mode. After this patch, old firmware with NORMAL type
    can still work well.

    The use of this new type is the same as before, so we add new type to
    avoid taking wrong firmware. Then, driver log can also give clear
    information about this change:

      rtw89_8852be 0000:03:00.0: Firmware version 0.29.26.0, cmd version 0, type 5
      rtw89_8852be 0000:03:00.0: Firmware version 0.29.26.0, cmd version 0, type 3
