sh: L-BOX RE2 support.
This adds support for the L-BOX RE2 router. http://www.nttcom.co.jp/l-box/ L-BOX RE2 is a SH7751R-based router. It has CF, Cardbus, serial, and LAN x2. This is one of the very few SH boards that a general person can obtain now. The L-BOX shipped with a 2.4.28 kernel, this is a rewritten patch adding it to current git.
