it821x: Add ultra_mask quirk for Vortex86SX
On Vortex86SX with IDE controller revision 0x11 ultra DMA must be disabled. This patch was tested by DMP and seems to work. It is a cleaned up version of their older Kernel patch: http://www.dmp.com.tw/tech/vortex86sx/patch-2.6.24-DMP.gz Tested-by: Shawn Lin <shawn@dmp.com.tw> Signed-off-by: Brandon Philips <bphilips@suse.de> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
