Krystian Pradzynski bfc87f9061 accel/ivpu/40xx: Allow to change profiling frequency
Profiling freq is a debug firmware feature. It switches default clock
to higher resolution for fine-grained and more accurate firmware task
profiling. We already configure it during boot up of VPU4.

Add debugfs knob and helpers per HW generation that allow to change it.
For vpu37xx the implementation is empty as profiling frequency can only
be changed on VPU4 or newer.
