[PATCH] fix drivers/ide/pci/siimage.c for PROC_FS=n

From: "Noah J. Misch" <noah@caltech.edu>

The Silicon Image driver is not building properly when CONFIG_PROC_FS is unset.
This patch corrects that problem.  It appears as though several utility
functions at the top of drivers/ide/pci/siimage.c that the driver always needs
accidentally fell within an #ifdef CONFIG_PROC_FS.  I also removed an excess
include while I noticed it.
