net: nvethernet: Allow driver to be built without NVPPS

Browse Source 
The nvethernet driver has a dependency on the NVPPS driver which in
turn has a dependency on the GTE driver. The GTE driver is being
transitioned to the new upstream HTE driver and while this transition is
on-going, allow the nvethernet driver to be distributed and built
without NVPPS and GTE.

Note that by default the dependency on the NVPPS driver is enabled by
setting CONFIG_TEGRA_NVPPS to 'y'. Only if the user sets
CONFIG_TEGRA_NVPPS to 'n' will it be disabled.
