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

Browse source

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

Replace manual macro/dcodec/mclk/npl/fsgen clock toggling with PM clock
helpers and runtime PM callbacks. Keep the SWR gate runtime PM reference
from SWR clock enable until disable so autosuspend does not gate clocks
while SWR is still prepared.

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_WSA_MACRO since this patch
introduces PM clock APIs.

Tighten error unwind by checking pm_runtime_put_sync_suspend() in probe and
by restoring regcache state if pm_clk_resume()/regcache_sync() fails.
