[PATCH v3] ARM: dts: AM43x: initial support

[PATCH v3] ARM: dts: AM43x: initial support

[Afzal Mohammed]

DT source (minimal) for AM4372 SoC to represent AM43x SoC's. Those
represented here are the minimal DT nodes necessary to get kernel
booting.

In DT nodes, "ti,hwmod" property has not been added, this would be
added along with PRCM support for AM43x.

v3: Make use of C preprocessor, rebased over Benoit's 'for_3.11/dts' branch
v2: Add gptimer 1ms, timer2, synctimer and remove twd local timer

Thanks Afzal. I've just applied it in my branch.
