[PATCH] generic PCI IDE support for Toshiba Piccolo chips

From: Daniel Drake <dsd@gentoo.org>

Adds Toshiba chips to the list supported by the generic PCI IDE driver.
The 2.4 tree already contained an entry for 0x1179:0x0102, this patch
adds that entry to 2.6 as well as two new ones (0x0103 and 0x0105).
This then allows DMA to be enabled on disks.
