gpu: nvgpu: gm20b: Require rework for DVFS and rg
Boards require a rework to make railgating and DVFS work realiably.
The information whether the board has been reworked or not will be
available on DTS.
This patch adds a DTS check to the GPU driver initialisation. If the
rework information is not available (or the rework has been marked as
disabled), railgating and DVFS are disabled.
