sata_sil: disable trim
When I connect an Intel SSD to SATA SIL controller (PCI ID 1095:3114), any
TRIM command results in I/O errors being reported in the log. There is
other similar error reported with TRIM and the SIL controller:
https://bugs.centos.org/view.php?id=5880
Apparently the controller doesn't support TRIM commands. This patch
disables TRIM support on the SATA SIL controller.
