Cássio Gabriel efca489a86 ALSA: msnd: add ISA and PnP system sleep callbacks 
The msnd drivers do not implement system sleep callbacks today, so
they have no defined way to recover DSP state after suspend.

Add common card suspend/resume helpers, rerun the DSP
initialization path on resume, restore the cached capture-source
state, and rearm the shared IRQ for already-open users.
