gpu: nvgpu: force CAR reset in do_idle() for gm20b
In gk20a_do_idle(), we wait for platform->railgate_delay
to allow GPU to go into rail gate
But sometimes we set platform->railgate_delay = INT_MAX
to disable GPU rail gating but allow it to suspend during
low power state
Due to this, force_idle API fails (it waits for INT_MAX)
To fix this, allow forcing CAR reset instead of rail gating
with flag "force_reset_in_do_idle" defined in gk20a_platform
Set this flag for gm20b until we fix the railgate_delay
