Subject: [PATCH 4/4] PCI: Drop Radeon quirk for Macbook Pro 8.2

commit 5938628c51a7 ("drm/radeon: make MacBook Pro d3_delay quirk more
generic") introduced a generic quirk for Macbook Pro 8.2s that contain
Radeon graphics to ensure that enough time had past when the device
was powered on.

As the PCI core now verifies the device is in D0 during power on this
extra artificial delay is no longer necessary.
