ath11k: send proper txpower and maxregpower values to firmware

Browse Source 
Set proper values for max_regpower, max_power, max_antenna_gain as it
is because firmware will convert power values to 0.5dbm steps by
multiplying it with 2.

If txpower is not set, it will lead to cca stuck resulting in latency
issues for QCN9074.

Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1-01386-QCAHKSWPL_SILICONZ-1
