wifi: ath12k: refactor SMPS configuration

Browse source 
Move fetching SMPS value to a new function and use u16_get_bits
to extract it from capabilities. This will help in extending the
functionality when SMPS support in 6 GHz band gets added in
subsequent patches.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
