    rtw88: update driver from upstream
    
    This is a combined version of updates of the rtw88 driver based
    on wireless-testing
    (wt-2023-05-11) 711dca0ca3d77414f8f346e564e9c8640147f40d (after v6.4-rc1),
    (wt-2023-06-09) 7bd20e011626ccc3ad53e57873452b1716fcfaaa (after v6.4-rc5),
    (wt-2023-07-24) 62e409149b62a285e89018e49b2e115757fb9022 (after v6.5-rc3),
    (wt-2023-08-06) 2a220a15be657a24868368892e3e2caba2115283 (after v6.5-rc4).
    
    This update follows other currently disconnected LinuxKPI based wireless
    drivers to lift them all to a same version in case someone else wants to
    work on this driver in parallel to predominant iwlwifi efforts.
    
    While debugging some funky register reads of 0xaeaea from RF_CFGCH
    resulting in "rtw880: [TXGAPK] unknown channel 234!!" more of these
    reads came to my attention hidden by using the register index rather
    than the defined value.  Make this more grep-able.
    
    Approved by:    re (gjb)
    
    (cherry picked from commit 90aac0d83bc9645f51ef0c2aeae6f9c0540bb031)
    (cherry picked from commit 4f3b2bba240b6e0603b5cbb47155fd8215bcbcb3)
    (cherry picked from commit 8323f69b8869ab714e329a378f632a55888d3fab)
