Safety build does not support vidmem. This patch compiles out vidmem
related changes - vidmem, dma alloc, cbc/acr/pmu alloc based on
vidmem and corresponding tests like pramin, page allocator &
gmmu_map_unmap_vidmem..
As vidmem is applicable only in case of DGPUs the code is compiled
out using CONFIG_NVGPU_DGPU.

g->ops.gr.enable_ctxsw()

Call the functions directly at all places
Remove CONFIG_NVGPU_DEBUGGER from places where these functions are
called since they are not debugger dependent
This also helps to disable CONFIG_NVGPU_DEBUGGER and to keep recovery

Board specific config is added in DT which will be parsed by nvgpu.
Nvgpu does the following.
1.Read gpio line number, interrupt type, and event delay from DT.
2.Call kernel methods and register the interrupt with kernel.
3.Create work queue which will process the interrupt in process context.
4.When interrupt occurs disable interrupt, add work to work queue.
