[PATCH] sonypi SPIC initialisation fix

Newer Sony VAIO models (VGN-S480, VGN-S460, VGN-S3XP etc) use a new method to
initialize the SPIC device.  The new way to initialize (and disable) the
device comes directly from the AML code in the _CRS, _SRS and _DIS methods
from the DSDT table.  This patch adds support for the new models.
