[PATCH 3/3] drm/tegra: sor: change io pad power state using new pmc api

[Venkat Reddy Talla <vreddytalla@xxxxxxxxxx>]

Added support in PMC driver to configure the power state and voltage level
of the IO pads from client driver via pincontrol framework, because of this
tegra_io_pad_power_disable() and tegra_io_pad_power_enable() deprecated,
to change power state of SOR io pads using new pmc apis.
