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.

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.

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.
