ipq806x: add LPASS clock control driver

Add a clock control driver to initialize the clock tree inside the
low-power audio subsystem. Depthcharge builds up on this to enable
audio function on storm.

The clock is hardcoded for 48KHz frame rate, two 16 bit channels.

BRANCH=storm
BUG=chrome-os-partner:35247

TEST=with depthcharge patches applied and Using depthcharge CLI audio
     test program verified that the target generates sensible sounds

     audio 100 100
     audio 1000 5000
