When sound wire master suspend is called, it holds the mutex lock
and does lpi_gpio_write, which gets preempted during pr_err_ratelimited.
Any other calls to master suspend will be blocked waiting for the above
mutex lock resulting in timeouts.
Remove pr_err_ratelimited log when device is down.

HW vote and unvote is currently called from multiple
clients leading to synchronization issues
during SSR/PDR scenarios. Synchronize all the vote requests
by using digital codec resource manager.

(cherry picked from commit 31aa875405)
Few Fixes on the drivers we are making are
1. snd_event is not resetting client info on deregister.
2. audio_prm is not providing the snd event up notification
3. gpr_lite reversing registration seq to avoid race condition
4. pinctrl-lpi reversing reg seq to avoid race condition.
