Tejal Kudav 79ee724b04 gpu: nvgpu: Add knob to control dbg/prof support ...

On production boards, there is requirement to disable GPU
profiler and debugger support. Add DT property 'support-gpu-tools'
which can be modified to enable/disable debugger/profiler support.
The default behavior is to enable the debugging features and set
'support-gpu-tools' to 1. This property is chosen to be u32 value
to be in sync with GPU vserser property by same name.
The debugger/profiler support is disabled by skipping the creation
of below nodes under /dev/nvgpu/:
1. ctxsw
2. dbg
3. prof
4. prof-dev
5. prof-ctx
