Add missing PL330 MDMA1 controller node to the device tree (DT).

[ Currently there is no problem with using 'non-secure' mdma1 address
  instead of 'secure' one on revision 0 of Exynos4210 SOC (as used by
  Universal C210 board) as this SOC revision is unsupported by DT. ]

Since mach-exynos4-dt.c is also going to be used for other SoCs from EXYNOS4
line, rename internal structures and functions to use exynos4_ prefix, instead
of exynos4210_.

Commit 171c067c ("ARM: EXYNOS: add support uart for EXYNOS4 and
EXYNOS5") renames S5P_PA_UARTn to EXYNOS4_PA_UARTn. Hence we
need to do similar modification in mach-exynos4-dt.c to fix
compilation error.

This commit brings exynos4-dt in line with recent changes to
mach-exynos tree, specifically:

 - Fixes build break related to replacing plat/exynos4.h with
   common.h in commit cc511b8d ("ARM: 7257/1: EXYNOS:
   introduce arch/arm/mach-exynos/common.[ch]")

 - Converts machine to use CONFIG_MULTI_IRQ_HANDLER as done for
   other machines in commit 4e44d2cb ("ARM: exynos4: convert
   to CONFIG_MULTI_IRQ_HANDLER")

 - Adds restart specifier as done for other machines in commit
   9eb48595 ("ARM: 7262/1: restart: EXYNOS: use new restart hook")

Add a new EXYNOS4 compatible device tree enabled board file. Boards
based on the EXYNOS4 family of SoC's can use this as the machine/board
file. When using this machine fike, a corresponding device tree blob
which describes the board's properties should be supplied at boot time
to the kernel.
