ASoC: wcd9xxx: Handle ADSP Subsystem Restart

Exercise codec reset as part of ADSP subsystem restart handling
and also update codec and ASoC cache registers to defaults. This
is required to clean up codec state post ADSP restart. Add flag
to avoid codec reset during device bootup.

If the software workaround to prevent leakage on the spkdrv is
enabled, handle the workaround post subsystem restart by turning
on PA and bandgap again.
