frequency adjustment function should work for all ASICs

[skot]

It looks like the power_management task has a loop to check for frequency changes, but it doesn't look like do_frequency_transition() is valid for all different ASIC types. This should probably be a function pointer in ASIC_functions to the proper ASIC-specific function to transition the frequency.
