b4036b1a0 tests/kms_content_protection: Add FB cleanup for MST tests
8d7c2453d tests/kms_content_protection: Pass crtc parameter and use per-CRTC FBs
925b14d43 tests/kms_content_protection: Add per-CRTC framebuffer infrastructure

The per-CRTC fb introduced in the commits caused regression especially
when the eDP panel is connected with 2 4k Panels connected through a
DP-MST hub with "-ENOSPC" and all the content protection tests are
failing.

The MST subtests are skipping when subtests are executed with "--r
dp-mst*" , as the MST changes introduced did not clean up properly
across subtests.

The create_fbs() now iterated through all crtcs and eDP (2k) claims the first
crtc before the larger output and fb is created with smaller size. Later when DP-4 maps to
the smae CRTC (it has differnt fb dimensions now 2k fb than the mode
required) , the kernel rejects the commits  with ENOSPC because of
invalid coordinates.
