linux/linux-titan-sh4: Update for the kernel. Add a patch which
enables scanning of pci function 1 even if function 0 doesn't exist.
This is required if using the upgraded BIOS in which one of the
ethernet cards is moved to function 1 and function 0 is wired up as a
bus-master pass-through from one of the mini-pci slots. So without
this patch you loose one of the lan interfaces when mini-pci slot A
is empty with the new BIOS. Also roll forward the linux-sh CVS date
to pick up a few more 2.6.17 fixes.
