fe320639c1 Revert "Revert "drm/amd/display: Implement zpos property""
This reverts commit e2066eb4efe0e7d2d329d6e6765ed637a523ac45.

The problematic IGT test case (i.e. kms_atomic@plane-immutable-zpos) has
been fixed as of commit cb77add45011 ("tests/kms_atomic: remove zpos <
N-planes assert") to the IGT repo. So, reintroduce the reverted code.

ea7e2edca8 drm/amd/display: always switch off ODM before committing more streams
ODM power optimization is only supported with single stream. When ODM
power optimization is enabled, we might not have enough free pipes for
enabling other stream. So when we are committing more than 1 stream we
should first switch off ODM power optimization to make room for new
stream and then allocating pipe resource for the new stream.

We wait for mpc idle while in a locked state, leading to potential

[What]
Move the wait_for_idle call to outside of HW lock. This and a
call to wait_drr_doublebuffer_pending_clear are moved added to a new
static helper function called wait_for_outstanding_hw_updates, to make
the interface clearer.

9ba46183eb drm/amd/display: rename function to add otg master for stream
We are renaming acquire first free pipe to add
otg master pipe for stream because the former name
doesn't indicate that it acquires the first free pipe
to use as an otg master pipe. This could cause coding
errors if someone uses it to acquire a different pipe type.
