Stop the siimage driver claiming SATA devices when the kernel is built for a LiveCD.

siimage SATA support for many is buggy (lost interrupts, etc.), and the driver is
unmaintained.  The libata drivers under CONFIG_SCSI_SATA work properly, perform
better, and are actively maintained.

We should not totally exclude the siimage driver from the LiveCD because it does support
PCI cards that provide extra IDE ports (non-SATA). However, to get SATA working, we need
to stop using this driver for SATA devices so that libata drivers can take effect.
This patch should be conditionally applied based on the setting of USE=livecd.
