Added NVGPU_DBG_GPU_IOCTL_SET_CTX_MMU_DEBUG_MODE ioctl to set MMU
debug mode for a given context.
Added gr.set_mmu_debug_mode HAL to change NV_PGPC_PRI_MMU_DEBUG_CTRL
for a given channel. HAL implementation for native case is
gm20b_gr_set_mmu_debug_mode. It internally uses regops, which directly
writes to the register if the context is resident, or writes to
gr context otherwise.
Added NVGPU_SUPPORT_SET_CTX_MMU_DEBUG_MODE to enable the feature.
NV_PGPC_PRI_MMU_DEBUG_CTRL has to be context switched in FECS ucode,
so the feature is only enabled on TU104 for now.

MISRA Rule 17.2 prohibits indirect recursion. nvgpu_allocator_initi()
was calling nvgpu_page_allocator_init(), which in turn was calling back
to nvgpu_allocator_init() to init a buddy allocator. Rather than
calling back to nvgpu_allocator_init(), have nvgpu_page_allocator_init()
call nvgpu_buddy_allocator_init() directly.
