qcacmn: Add min_psd changes for best power mode

Browse Source 
Add reg txops to fetch min_psd for punctured SP channels.
min_psd is computed from afc response. Using the min_psd power value,
EIRP is computed for the non-punctured BW using the formula
EIRP = PSD + 10 * log10(non-punctured BW).
Add an entry in bw_to_10log10_map for all possible non-punctured
bandwidth.
