gpu: nvgpu: vgpu: modify tsg enable sequence

Browse Source 
TSG enable sequence in native has been modified due to a
hardware bug requiring enabling all channels with NEXT and
CTX_RELOAD set in a TSG, and then enabling rest of
channels.However it is not possible to check if NEXT and
CTX_RELOAD is set in vgpu. Have a separate implementation
for enabling tsg sequence in vgpu till the fix for
hardware bug is implemented for virtualized configuration.

Bug 200348087
