[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.
