ASoC: codecs: lpass-va-macro: Switch to PM clock framework for runtime PM

Browse source

Convert the LPASS VA macro codec driver to runtime PM clock management by
using the PM clock framework.

Replace manual macro/dcodec/mclk/npl clock handling with PM clock helpers
and runtime PM callbacks, and keep runtime PM references around fsgen clock
gating so PM-clock-managed clocks remain active while fsgen is enabled.

Set autosuspend delay to 100 ms so PM-clock-managed votes are dropped soon
after idle while still avoiding suspend/resume churn on short gaps.

Add a PM_CLK dependency to SND_SOC_LPASS_VA_MACRO since this patch
introduces PM clock APIs.

Improve failure unwind paths: handle runtime PM put errors in probe/fsgen
paths and restore regcache state correctly on resume failure.
