wifi: ath12k: fix endianness handling while accessing wmi service bit

Browse Source 
Currently there is no endian conversion in ath12k_wmi_tlv_services_parser()
so the service bit parsing will be incorrect on a big endian platform and
to fix this by using appropriate endian conversion.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00217-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
