gpu: nvgpu: poweron host1x explicitly
Currently gk20a gets reference of host1x via phandle in
Device Tree. But runtime PM does not seem to be handling power
dependencies too well in this case and hence some times host1x
is off when we need it.
To fix this, exlicitly power on host1x while powering gpu up.
Do this via "busy" and "idle" callbacks from gk20a_platform
