On the QCM6490 boards the LPASS firmware controls the complete clock
controller functionalities. But the LPASS resets are required to be
controlled from the high level OS. The Audio SW driver should be able to
assert/deassert the audio resets as required. Thus in clock driver add
support for the same.
