mainboard/ms7721: Copy files from "asus/f2a85-m" to "msi/ms7721".

This patch adds a copy of the Asus F2A85-M code with only minimal changes.
(to ensure that the code compiles)

A second commit will be published to remove the copied code parts that
don't apply to the MS-7221 and to make everything else actually work
on the MS-7221 board.
