From: Ben Dooks <ben.dooks@codethink.co.uk>
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.
