MISRA rule 13.5 doesn't allow right-hand operand of logical && or ||
operator to have persistent side effects. The reason is right-hand
operand is executed or checked depending on the left-hand operand value.
That means side effects in the right-hand operand may or may not occur,
contrary to programmer's expectation. Hence, this rule is implemented to
avoid unexpected behavior.
This patch divides if condition with logical && operator to nested if
conditions to resolve this violation.

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.
