ALSA: es1688: add ISA suspend and resume callbacks

The ISA ES1688 driver still carries a disabled suspend/resume block in
its isa_driver definition, while the same file already provides minimal
power-management handling for the PnP ES968 path.

Add ISA-specific PM callbacks and factor the existing ES1688 suspend and
resume sequence into common card-level helpers shared by both probe
paths. Suspend moves the card to D3hot. Resume reinitializes the chip
with snd_es1688_reset() and restores the card to D0, propagating reset
failures to the caller.

This wires up power-management callbacks for the ISA path and keeps the
PM handling consistent between the ISA and PnP probe paths.
