[PATCH] m32r: Support M32104UT target platform

Browse source 
This patch is for supporting a new target platform, Renesas M32104UT
evaluation board.

The M32104UT is an eval board based on an uT-Engine specification.  This board
has an MMU-less M32R family processor, M32104.
http://www-wa0.personal-media.co.jp/pmc/archive/te/te_m32104_e.pdf

This board is one of the most popular M32R platform, so we have ported
Linux/M32R to it.
