sh: Reworked SH7780 PCI initialization.
This consolidates the PCI initialization code for all of the pci-sh7780 users, and sets up the memory window dynamically as opposed to using hardcoded window positions. A number of bugs were fixed at the same time, including the PIO handling and master abort timeout settings being incorrect. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
