[PATCH] drm/radeon: revert Apple re-POST hack

[alexdeucher at gmail.com]

From: Alex Deucher <alexander.deucher at amd.com>

This reverts:
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 may not be required any more due to other
fixes for UEFI on non-Mac platforms, but I don't have any Macs.

Fixes:
