sh: landisk updates.
Updates for the landisk board: - The push_switch framework was used. - landisk_pwb.c was divided into psw.c and gio.c. - pata_platform was supported in USL-5P. - irq.c was rewritten. - io.c was replaced with generic I/O routines. Signed-off-by: kogiidena <kogiidena@eggplant.ddo.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
