sh: SH-2007 board support.

This patch series adds support for ITO Co., Ltd.'s SH-2007 reference
platform (A PC-104 based SH7780 platform).

This is a direct port of the out-of-tree board support from the vendor's
kernel, originally located at:

	http://ms-n.org/sh-linux/kernel/

More information on the board and the vendor can be obtained from the
vendor's site at:

	http://www.itonet.co.jp/

Presently supported peripherals are CF and ethernet, with support for
the on-board IDE still pending further testing.
