gpu: nvgpu: fix reset clock in gm20b
To assert reset on GPU, we store "gpu_ref" clock in
platform->clk[0] and use it to assert/deassert reset
But for gm20b, "gpu_ref" is no longer resettable.
To fix this, add two callbacks in gk20a_platform :
.reset_assert and .reset_deassert
Also, add a pointer "clk_reset" to store the clock
which needs to be reset
For gk20a specific implementation, we continue to
reset platform->clk[0]
For gm20b specific implementation, we first request
"gpu_gate" clock, store it and use it to assert reset
