Add support for the lpass clock controller found on SC8280XP based devices.
This would allow lpass peripheral loader drivers to control the clocks and
bring the subsystems out of reset.

Currently this patch only supports resets as the Q6DSP is in control of
LPASS IP which manages most of the clocks via Q6PRM service on GPR rpmsg
channel.

Say Y if you want to use the LPASS branch clocks of the LPASS clock
controller to reset the LPASS subsystem.

Thanks, Will do that in v3.
