qcacmn: Find best 6 GHz power type for connection

Browse source 
Find the best 6 GHz power type for connection
according to following regulatory policy:
1) SP power type is selected only if AP advertises
   SP and client supports SP.
2) LPI power type is selected only if AP advertises
   LPI and client supports LPI.
3) VLP power type is selected for the below cases,
   a) AP advertises VLP and client supports VLP
   b) AP advertises SP but client doesn't support
      SP but supports VLP.
   c) AP advertises LPI but client doesn't support
      LPI but supports VLP.
