drm/radeon: disable runtime pm on PX laptops without dGPU power control

Browse source

commit e64c952efb upstream.

Some PX laptops don't provide an ACPI method to control dGPU power.  On
those systems, the driver is responsible for handling the dGPU power
state.  Disable runtime PM on them until support for this is implemented.
