Subject: [PATCH 22/32] ARM: bcm2835: Include SDHOST in the device tree.

From: Eric Anholt <eric@...olt.net>

It's disabled by default, and will be enabled by a particular board's
DT.  The DMA channels are also currently left out, because our DMA
engine support doesn't yet include slave SG, and there doesn't appear
to be a clean way to include "does slave SG" in the channel
request/config process.
