sh: Set the default I/O port base to P2SEG.
This bumps up the default I/O base to P2SEG, which allows legacy probing to bail out gracefully rather than oopsing. Platforms that have a real PIO offset still need to fix this up on their own, although most platforms are content with P2SEG already. The previous change to teach ioport_map() about >= P1SEG offsets in combination with this patch allows both the already remapped and the legacy address probing to pass through and succeed. Fixes up an oops with i8042 on the sh7785lcr board. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
