ALSA: gusclassic: add ISA suspend and resume callbacks

Browse Source 
gusclassic still leaves its ISA PM callbacks disabled because the shared
GF1 core had no suspend and resume path suitable for PM recovery.

Wire the driver up to the new shared GUS suspend and resume helpers so a
suspend/resume cycle restores usable GF1 operation without rerunning
probe-only detection or tearing down the runtime bookkeeping kept by the
card instance.
