drm/amd/display: Rebuild mapped resources after pipe split

[ Upstream commit 387596ef2859c37d564ce15abddbc9063a132e2c ]

[why]
The issue is specific for linux, as on timings such as 8K@60
or 4K@144 DSC should be working in combination with ODM Combine
in order to ensure that we can run those timings. The validation
for those timings was passing, but when pipe split was happening
second pipe wasn't being programmed.

[how]
Rebuild mapped resources if we split stream for ODM.
