ALSA: opti9xx: restore snd-miro state after resume

snd-miro has no PM callbacks, so system resume leaves the OPTi
master-control registers and the board-specific ACI mixer state
unrestored.

Like snd-opti9xx, the driver needs to reprogram the OPTi routing
registers before bringing the codec back. snd-miro also keeps mixer
state in the ACI block, so the codec resume callback alone is not
enough here. Save the ACI mixer state on suspend, reinitialize the
OPTi and ACI state on resume, replay the saved ACI values, and then
resume the WSS codec. Hook the PM handlers into both the ISA and PnP
paths.

Also initialize miro->card on the ISA path for the existing dev_*()
logging and keep the cached solo-mode value aligned with the value
written to hardware.

PCM20 radio tuner state remains outside this driver's PM scope.
