drm/radeon: narrow scope of Apple re-POST hack
This narrows the scope of the apple re-POST hack added in: drm/radeon: re-POST the asic on Apple hardware when booted via EFI That patch prevents UVD from working on macs when booted in EFI mode. The original patch fixed macbook2,1 systems which were r5xx and hence have no UVD. Limit the hack to those systems to prevent UVD breakage on newer systems.
