wifi: ath12k: Segregate the common and wifi7 specific structures

Segregate the common and wifi7 specific structures in hal,
and move them to corresponding header files.

hal.h file in common directory is used by both common
and wifi7 directory files, while hal.h and other hal headers
are used only by files within the wifi7 directory since
these headers contain hw specific hal data.
