[PATCH V2] regulator: dt: fix the name of regulator supply

[Laxman Dewangan <ldewangan@nvidia.com>]

If there is any input supply for regulator then the name
of supply need to provided by init_data->supply_regulator.
In dt case, the input supply is searched by the <name>-supply
and here it is require to fix the name so that correct device
node can be identified at the time of regulator registration.

Fixing the name for input supply as "regulator-supply".
