wifi: cfg80211: save power spectral density(psd) of regulatory rule
6 GHz regulatory domains introduces Power Spectral Density (PSD).
The PSD value of the regulatory rule should be taken into effect
for the ieee80211_channels falling into that particular regulatory
rule. Save the values in the channel which has PSD value and add
nl80211 attributes accordingly to handle it.
