drm/radeon: update line buffer allocation for dce6

We need to allocate line buffer to each display when
setting up the watermarks.  Failure to do so can lead
to a blank screen.  This fixes blank screen problems
on dce6 asics.

Fixes:

Based on an initial fix from:
Jay Cornwall <jay.cornwall@amd.com>
