ALSA: sc6000: Restore board setup across suspend

snd_wss_resume() restores only the codec register image.  The SC-6000
driver also programs card-specific DSP routing and enters MSS mode
during probe, and that setup is not replayed after suspend.

Cache the WSS chip pointer in the SC-6000 card state and wire ISA
suspend and resume callbacks to the shared board-programming helper,
so the board is reinitialized before the codec state is restored.

This keeps the old/new DSP split in one place and restores the
board-level MSS setup that the codec resume path does not cover.
