Sagar Kamble a16cc2dde3 gpu: nvgpu: compile out vidmem from safety build
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.
