[76/91] drm/radeon/kms: fix sideport detection on newer rs880 boards

[Greg KH]

2.6.34-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Alex Deucher <alexdeucher@xxxxxxxxx>

commit 4b80d954a7e54c13a5063af18d01719ad6a0daf3 upstream.

The meaning of ucMemoryType changed on recent boards, however,
ulBootUpSidePortClock should be set properly across all boards.
