gpu: nvgpu: Define CONFIG_TEGRA_VIRTUALIZATION ccflag

Browse Source 
When building NVGPU with virtualization enabled, we need to ensure that
the ccflag CONFIG_TEGRA_VIRTUALIZATION is defined. The Tegra HV driver
is only compiled when CONFIG_TEGRA_VIRTUALIZATION is defined. When NVGPU
is compiled without defining CONFIG_TEGRA_VIRTUALIZATION, then function
stubs in the header file "soc/tegra/virt/hv-ivc.h" will be used and these
stubs will return an error when called causing virtualization to fail.
