Subject: drm/amd/display: wait for test pattern after when all pipes are
Git-commit: 4134aaa11bd9c3e65ec07a1fcd59f57d4c58c434
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
 programmed

[why]
Currently we wait for test pattern after each pipe is programmed.  For
ODM combined scenario it will cause test pattern is shown on only half
screen for 1 frame. This is not desirable.

[how]
No wait between odm pipe programming, only wait after all pipes are
programmed.
