wifi: ath12k: Convert ath12k_dp member in ath12k_base to pointer

Browse source 
Currently, the Data Path (DP) specific device object (ath12k_dp) is
embedded directly within the ath12k_base structure. The DP object cannot
be extended with architecture-specific fields within a contiguous memory
block with this design.

To address this, convert ath12k_dp into a dynamically allocated object
and store it as a pointer in ath12k_base. This change allows allocation
and initialization of ath12k_dp based on the underlying hardware
architecture. Architecture-specific fields can now be maintained as
private data within a contiguous memory block of ath12k_dp.

This patch (and the forthcoming patches) are intended to serve the purpose
of refactoring different DP objects for the Next Generation ath12k
driver.
