qcacmn: Modify tx-power in Regdomain FCC15 and FCC16

The max txpower allowed in reg domain FCC15 (24dBm) and FCC16 (30 dBm)
as per the regulatory update #32 xls is applicable for 320 mhz. For
160 MHz,the powers need to be reduced by 3dbm.

This was missed in the change-id
I1b1bdaceb4fa48973fb33fca17465a25d05ae040, and the power values
applicable for 320MHz were added.

Therefore, modify the max txpower allowed in regdomain FCC15 as 21 dBm
and the max txpower allowed in regdomain FCC16 as 27 dBm.
