drivers/intel/gma: Do not rely on CBLV in OpRegion Mailbox3
CBLV is not kept up to date by Linux' i915. We should fix that too,
but it will likely take some years until we can always expect it to
work.
For now read the register values directly. To accomodate that we
are not the only one writing those, revise XBQC() to search for
the closest value in BRIG (instead of a lower equal one) and round
more accurately for better matches.
