The two versions of the structure are obviously derived from the same
one, but have diverged over time, before they got added to the kernel.
This moves the structure to a new shared header file and uses the superset
of the members, to ensure the interfaces are all compatible.

Fixes compute rings test failure on bare metal during full GPU reset.
RCA:
the ring buffer has to be filled with valid packets (such as NOPs) first
before submitting MAP_QUEUEs packet into KIQ. Once a compute engine is mapped,
it will immediately execute the ring buffer if the RTPR is not equal to the
WTPR from the MQD. It could lead to engine hang if the ring buffer filled

drm/amd/display: revert to hacking bounding box for pipe split
Directly editing pipe config outside of formula is error prone
and results in higher clocks being used when splitting.
For this reason we reverted to using bounding box hacking
to split. Since sometimes this erroneusly results in higher dpm
being required we unhack the bounding box and recalculate to allow
dpm0 is possible.
Side effect is we will lose some stutter efficiency
in non dpm0 cases. This is not a big concern since increased stutter
efficiency saves an order of magnitude less power than lower dpm.
