wifi: ath12k: Pass correct values of center freq1 and center freq2 for 320 MHz

Currently, for 320 MHz bandwidth, center frequency1 and
center frequency2 are not passed correctly to the firmware.
Set center frequency1 as the center frequency of the
primary 160 MHz channel segment and center frequency2 as the center
frequency of the 320 MHz channel and pass the values
to the firmware.
