gpu: nvgpu: Power on platform deps for wfi
Currently gk20a_channel_idle() drops pm_runtime references to gk20a
and then drops platform dependencies. As we usually delay powering down
gk20a, we may end up to case where the platform dependencies are
turned off at the moment we start powering down gk20a. Power off
sequence may use platform dependencies for informing completion of
the last work, wait-for-idle, and therefore we may simply drop the
information about job completion.
This patch adds missing calls to power up platform dependencies for
the time we submit the last work.
