sh: Establish a SuperHyway<->PCIe window mapping on SH7786 PCIe.
This bumps up the low address to match the physical memory windows for SHway<->PCIe transfers. The previous implementation was banking on a 1:1 virt<->phys SHway mapping, which doesn't apply here. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
