Supply names are renamed from vmmc -> mmc and vmmc_aux -> mmc_aux.
This is done to have simple supply names both in the driver
and in the board-evm file.

It will break all existing OMAP3 boards.

ditto.

[Aggarwal, Anuj] This was done to have the same naming conventions across
the board. I could not find an extra "v" in supply names except MMC.
Hence modified this. Regulator supply names should be simple and easy to
understand.
I can revert this change or change the dependent board files for SDP/LDP
etc. What do you suggest?

Extra 'v' letter that stands for "voltage" does not make naming
conventions simpler. Moreover, VMMC, VDAC etc directly correspond to
PMIC datasheet naming convention. Please revert the change and keep
"v" in the regulator name.

These names normally come from the names of the supplies in the
datasheets for the consumer devices rather than the names of the rails
on the boards - those would normally be specified as the names in the
constraints where they are used for display purposes.
