[PATCH 3/3] ARM: at91/dt: sama5d3 add gpio regulator for vmmc0

[Ben Dooks <ben.dooks-4yDnlxn2s6sWdaTGBSpHTA@public.gmane.org>]

Add gpio regulator for vmmc0 and attach the vmmc for it to the mmc0
node on the SAM5D3 Xplained board. This will remove the following
warning from the kernel:

atmel_mci f0000000.mmc: No vmmc regulator found

Note, atmel_defconfig will need gpio regulator support enabled if this
is to be used properly.
