[PATCH v2 3/4] ARM: LG Optimus Black (P970) codename sniper support, with basic features

[Paul Kocialkowski <contact@paulk.fr>]

The LG Optimus Black (P970) codename sniper is a smartphone that was designed
and manufactured by LG Electronics (LGE) and released back in 2011.
It is using an OMAP3630 SoC, GP version.

This adds devicetree support for the device, with only a few basic features
supported, such as debug uart, i2c, internal emmc and external mmc.
