Wesley Chalmers 6209542869 drm/amd/display: Use the largest vready_offset in pipe group 
[ Upstream commit 5842abd985 ]

[WHY]
Corruption can occur in LB if vready_offset is not large enough.
DML calculates vready_offset for each pipe, but we currently select the
top pipe's vready_offset, which is not necessarily enough for all pipes
in the group.

[HOW]
Wherever program_global_sync is currently called, iterate through the
entire pipe group and find the highest vready_offset.
