Srinivas Kandagatla 1c5be81573 ASoC: codecs: va-macro: use fsgen as clock
[ Upstream commit 30097967e0566cac817273ef76add100f6b0f463 ]

VA Macro fsgen clock is supplied to other LPASS Macros using proper
clock apis, however the internal user uses the registers directly without
clk apis. This approch has race condition where in external users of
the clock might cut the clock while VA macro is actively using this.

Moving the internal usage to clk apis would provide a proper refcounting
and avoid such race conditions.

This issue was noticed while headset was pulled out while recording is
in progress and shifting record patch to DMIC.
