asoc: lpass-cdc: add put_autosuspend to pair with pm_runtime_get_sync

When reading/writing lpass codec registers, pm_runtime_put_autosuspend
is missed when vote fails and it causes device fails suspending after
ssr. Add pm_runtime_put_autosuspend to pair with pm_runtime_get_sync.
When LPASS_CDC_MACRO_EVT_PRE_SSR_UP comes, core vote is needed before
resetting GFMUX reg and dev_up is not set to true yet. Add pre_dev_up
flag to indicate PRE_SSR_UP and be used in lpass_cdc_check_core_votes
to avoid false alarm.
