* gpu: nvgpu: use refcnt for ch mmu_debug_modeThomas Fleury2020-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Replaced ch->mmu_debug_mode_enabled with ch->mmu_debug_mode_refcnt. If channel is enabled multiple times by userspace, then ref count is updated accordingly. There is an expectation that enable/disable calls are balanced for setting channel's mmu debug mode. When unbinding the channel, decrease refcnt for the channel until it reaches 0. Also, removed tsg parameter from nvgpu_tsg_set_mmu_debug_mode as it can be retrieved from ch.

* gpu: nvgpu: add refcounting for MMU debug modeThomas Fleury2020-01-30
| | | | | | | | | | | | | | | | | | | | | | | GPC MMU debug mode should be set if at least one channel in the TSG has requested it. Add refcounting for MMU debug mode, to make sure debug mode is disabled only when no channel in the TSG is using it.
