[PATCHv4] ARM: dts: sunxi: Add a olinuxino-lime2-emmc

[Olliver Schinagl]

There are 3 kinds of OLinuXino Lime2 boards.
One without any on board storage, one with NAND storage and one with
eMMC storage. This patch adds the eMMC variant of boards.

eMMC storage is different from a regular SD card in that it is soldered
on the board and cannot be changed. Additionally, it shares pins with
the NAND module and with the second SPI port.

Changeslog:

v4:
  Add board compatibles

v3:
  Add pwr-seq-emmc with the reset gpio

v2:
  Remove unsupported no-1.8-v property, add vqmmc property

v1:
  Initial bare bone version

This is not something we want in the commit log. This should go below
the --- so that it's dropped when applied.

Removed and applied.

Thanks,

Sorry about that, I didn't know the --- trick. ChenYu reminded of it 
however, so that'll go into my toolblox.
