wifi: ath12k: Add framework for hardware specific DP interrupt handler

Browse Source 
Currently, the DP service SRNG handler is invoked directly from the NAPI
poll handler, which prevents using different handlers for different
architectures. To fix this, introduce a DP architecture-ops table to
invoke architecture specific handler from NAPI poll handler. Future patches
will leverage this framework to invoke architecture-specific handlers from
common code.

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