wifi: ath12k: Remove the wifi7 header inclusions in common code

As a precursor to the movement of wifi7 specific .c files to
ath12k_wifi7.ko module, remove the wifi7 headers included
in the common .c files except for dp_mon.c file, as the changes
for moving the code from common to wifi7 directory for monitor
will be coming incrementally.

Since, dp_mon.c continues to be part of ath12k.ko module,
add a few callbacks in hal_ops to facilitate calls from
dp_mon.c to reach hal APIs present in ath12k_wifi7.ko module
