[PATCH V6 08/10] soc: tegra: pmc: Move powergate definitions to dt-bindings

[Jon Hunter <jonathanh-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

Move the Tegra Powergate definitions into include/dt-bindings so that
these can be used by the powergate bindings in device-tree source files.

Remove the TEGRA_POWERGATE_3D0 definition as this is an alias and is
not used anywhere.
