[PATCH 1/3] ARM: at91/dt: sama5d3 fill in mmc1 and default disabled

[Ben Dooks]

The mmc1 channel is not populated on the SAM5D3 Xplained board, however
it is enabled and therefore the driver is attaching to it.

The node configuration for mmc1 is missing, so add an mmc1 node in the
device tree so add the basic node, set it to default it to disabled. Also
add the vmmc and also the necessary slot configuration if this node
where to be enabled to avoid the following warnings from the driver.

atmel_mci f8000000.mmc: No vmmc regulator found
atmel_mci f8000000.mmc: No vqmmc regulator found
