[ARM] 5210/2: AFEB9260: board support

This patch adds support for AT91SAM9260-based board AFEB9260
which is a product from both Open Source design which runs
Open Source software. Some commertial projects
are made with this design. A board is basically AT91SAM9260-EK
with some modifications and different peripherals and different
parts used. Main purpose of this project is to gain experience in
hardware design.

(In Russian only, sorry).
Subversion repository: svn://194.85.238.22/home/users/george/svn/arm9eb

By this patch only basic functionality is provided.
