ALSA: ymfpci: Store additional legacy registers on suspend
YMF744 and newer store the base IO ports in separate PCI config registers.
Since these registers were not restored, when set to a non-default value,
features that rely on them (FM, MPU401, gameport) were not functional
after restore, as their respective IO ports were reset to their defaults.
