wifi: ath12k: relocate ath12k_dp_pdev_pre_alloc() call

Currently, the data path pdev pre alloc and mac allocate are called
separately from the core start procedure. The data path pdev pre alloc
can be called from the mac allocate procedure itself since initialization
related to pdev happens in the mac allocate procedure. So move the caller
of DP pdev pre alloc from the core start procedure to the mac allocate
procedure. This change helps in the future to easily decouple the mac
allocate procedure from core start handling in order to support MLO in
multi chip.
