gpu: nvgpu: do channel resume after hw init
During finalize power on, resume channels only after
complete hw initialization is done. Otherwise it will
cause issues with unexpected usage of hw. During first
boot will not see these issues because there will no channels.
But after rail gate/ungate or suspend/resume these issues
can be seen if channels are present before rail-gate/suspend.
