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)
Remove reslock usage from device wakeup vote and unvote functions.
Mutex lock 'reslock' is to used only within runtime resume
and suspend functions, to avoid race conditions between them.

During SSR and headset detection/removal interrupt
concurrencies, ssr_lock can lead to serv reg ack timeout
issues. Remove this synchronization to avoid this issue.

Headset is not detected if devnum 0 gets detached at bootup.
This is because on detach being called hw will mask interrupt
at slave side but will not unmask it afterwards.
Also device 0 is used only for discovery purpose and
interrupt shouldnt be masked if it detaches.
