[Patch v1 1/5] drm/amdgpu: always enable runtime power management

[Rajneesh Bhardwaj]

This allows runtime power management to kick in on amdgpu driver when
the underlying hardware supports either BOCO or BACO. This can still be
avoided if boot arg amdgpu.runpm = 0 is supplied.

	BOCO: Bus Off, Chip Off
	BACO: Bus Alive, Chip Off
