A bit smaller this time around.. there are still a couple uabi
additions for vulkan waiting in the wings, but I punted on them this
cycle due to running low on time. (They should be easy enough to
rebase, and if it is a problem for anyone I can push a next+uabi
branch so that tu work can proceed.)
The bigger change is refactoring dpu resource manager and moving dpu
to use atomic global state. Other than that, it is mostly cleanups
and fixes.

Move mapping of resources to encoder ids from the resource manager to a
new dpu_global_state struct. Store this struct in global atomic state.
Before this patch, atomic test would be performed by modifying global
state (resource manager), and backing out any changes if the test fails.
By using drm atomic global state, this is not necessary as any changes
to the global state will be discarded if the test fails.

Track hardware resource objects in arrays rather than
a list and remove the resource manager's iterator idiom. Separate
the mapping of hardware resources to an encoder ID into a different
array.
Use an implicit mapping between the hardware blocks' ids, which
are 1-based, and array indices in these arrays to replace iteration
with index lookups in several places.

With the db845c running AOSP, I see the following error on every
frame on the home screen:
[drm:dpu_plane_atomic_check:915] [dpu error]plane33 invalid src 2880x1620+0+470 line:2560
This is due to the error paths in atomic_check using
DPU_ERROR_PLANE(), and the drm_hwcomposer using atomic_check
to decide how to composite the frame (thus it expects to see
atomic_check to fail).
In order to avoid spamming the logs, this patch converts the
DPU_ERROR_PLANE() calls to DPU_DEBUG_PLANE() calls in
atomic_check.

Current code assumes that all the irqs registers offsets can be
accessed in all the hw revisions; this is not the case for some
targets that should not access some of the irq registers.
This change adds the support to selectively remove the irqs that
are not supported in some of the hw revisions.
Changes in v1:
- Add support to selectively remove the hw irqs that are not
not supported.
Changes in v2:
- Remove unrelated changes.
Changes in v3:
- Remove change-id (Stephen Boyd).
- Add colon in variable description to match kernel-doc (Stephen Boyd).
- Change macro-y way of variable description (Jordon Crouse).
- Remove unnecessary if checks (Jordon Crouse).
- Remove extra blank line (Jordon Crouse).
