rtw89: extend subband for 6G band

Browse Source 
Split 6G band into 8 sub-bands where indexes are from 0 to 7,
i.e. RTW89_CH_6G_BAND_IDX[0-7]. Then, decide subband by both
band and channel instead of just channel because conflicts
between 5G channels and 6G channels.

Moreover, add default case to the existing use of switch (subband).
