drm/amd/display: update pipe selection policy to check head pipe
commit 8fef253c94a5312b9150b2ff8e633b331bac7e88 upstream.
[Why]
No check on head pipe during the dml to dc hw mapping will allow illegal
pipe usage. This will result in a wrong pipe topology to cause mpcc tree
totally mess up then cause a display hang.
[How]
Avoid to use the pipe is head in all check and avoid ODM slice during
preferred pipe check.
