Deepak Nibade 3684ed8fd6 gpu: nvgpu: use railgate instead of reset_assert ...

In gk20a_do_idle(), if can_railgate = false, we do
reset_assert() on the GPU

But asserting reset might have dependencies on
specific h/w seqeunce for ensuring proper reset

Hence avoid calling reset_assert() and directly
call platform specific unrailgate() and railgate()
APIs which take care of the correct reset sequence
