Add support for the Cyrix/NatSemi Geode SC5530 chips. This driver is ported from oss/kahlua.c and is made up of two patches.

Patch 1/2 adds some stuff to the SB layer to allow for some hardware quirks and is to be applied to alsa-kernel. Patch 2/2 adds the actual driver code to be applied to alsa-driver. Patch 2 depends on patch 1.
