gpu: nvgpu: add target refcount for gk20a_wait_for_idle()
API gk20a_wait_for_idle() right now always waits for
0 usage count
But in case railgating is disabled through sysfs,
usage count will never get to 0
Hence in this case we should wait for usage count
of 1
If platform->user_railgate_disabled is set,
keep target usage count of 1, otherwise keep
target usage count as 0
