Terje Bergstrom 2aead8a72f gpu: nvgpu: Disable only channel at zcull bind ...

At zcull bind we disable whole GR engine. This is unnecessary, so
instead disable only the channel and make sure it's unloaded.

Introduces also an API in fifo_gk20a.c to do the channel disable.

gr_gk20a_ctx_zcull_setup() was always passed true as last parameter,
so remove parameter.
