gpu: nvgpu: vgpu: modify tsg enable sequence
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
