ARM: EXYNOS4: Add support SMDK4412 Board
authorChanghwan Youn <chaos.youn@samsung.com>
Tue, 4 Oct 2011 08:09:26 +0000 (17:09 +0900)

SMDK4412 board is same as a SMDK4212 board except that
it has EXYNOS4412 SoC, thus it can share machine code
with SMDK4212.

This patch renames mach-smdk4212.c to mach-smdk4x12.c
to support both SMDK4212 and SMDK4412 board with one
machine file.
