gpu: nvgpu: use refcnt for ch mmu_debug_mode
...
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 mode
...
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.

replace tsgid with a pointer to a struct tsg_gk20a in the function
gk20a_fifo_tsg_abort(). gk20a_fifo_tsg_abort needs to enumerate through
all the channels within the tsg as well as pass the tsg pointer to
other functions, qualifying the need to use a pointer instead as an
input parameter.
