Konsta Holtta 5e68c6e971 gpu: nvgpu: add support for refcount tracking ...

If enabled, track actions (gets and puts) on channel reference counters.
Dump the most recent actions to syslog when
gk20a_wait_until_counter_is_N gets stuck when closing a channel.
GK20A_CHANNEL_REFCOUNT_TRACKING specifies the size of the action
history. Default is to disable completely, as this has some runtime
overhead.
