From: Ben Dooks <ben.dooks@xxxxxxxxxxxxxxx>
Add fixed 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 fixed regulator support enabled if this
is to be used properly.

[use a fixed regulator instead of gpio one]
