wifi: ath12k: Add direct HAL pointer in ath12k_dp

Browse Source 
Add a direct pointer to the HAL context in ath12k_dp. Since ath12k_dp
is frequenctly used in the per-packet data path, this avoids the need
to access the HAL handle through the ab pointer, reducing indirection
in the per-packet data path.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
