The pipe's layout is not cached, corresponding data structure is zeroed
out each time in the dpu_plane_sspp_atomic_update(), right before the
call to _dpu_plane_set_scanout() -> dpu_format_populate_layout().
Drop plane_addr comparison against previous layout and corresponding
EAGAIN handling.

As SSPP blocks are now visible through dpu_kms->rm.sspp_blocks, move
SSPP debugfs creation from dpu_plane to dpu_kms. We are going to break
the 1:1 correspondence between planes and SSPPs, so it makes no sense
anymore to create SSPP debugfs entries in dpu_plane.c

Follow the example of all other hw blocks and initialize SSPP blocks in
Resource Manager.

For all hardware blocks except SSPP the corresponding struct is named
after the block. Rename dpu_hw_pipe (SSPP structure) to dpu_hw_sspp.
Also rename struct dpu_hw_pipe_cfg to dpu_hw_sspp_cfg to follow this
change.

Commit da7716a249b699978fb5 ("drm/msm/dpu: Add support for XR30 format") enabled
support for the 10-bit XR30 color format but missed enabling support for the
corresponding per-pixel alpha-blending AR30 color format.
Declaring only XR30 but not AR30 color format support can trigger bugs in
userspace. KDE KWin compositor versions prior to 5.27.3 for example prefer
10-bit color formats, rendering a 1cm^2 black box around the cursor due to
missing per-pixel alpha-blending.

Flush mechanism for DSPP blocks has changed in sc7280 family, it
allows individual sub blocks to be flushed in coordination with
master flush control.
Representation: master_flush && (PCC_flush | IGC_flush .. etc )
This change adds necessary support for the above design.
Changes in v1:
- Few nits (Doug, Dmitry)
- Restrict sub-block flush programming to dpu_hw_ctl file (Dmitry)
Changes in v2:
- Move the address offset to flush macro (Dmitry)
- Separate ops for the sub block flush (Dmitry)
Changes in v3:
- Reuse the DPU_DSPP_xx enum instead of a new one (Dmitry)
Changes in v4:
- Use shorter version for unsigned int (Stephen)
Changes in v5:
- Spurious patch please ignore.
Changes in v6:
- Add SOB tag (Doug, Dmitry)
Changes in v7:
- Cache flush mask per dspp (Dmitry)
- Few nits (Marijn)
Changes in v8:
- Few nits (Marijn)
Changes in v9:
- Use DSPP enum while accessing flush mask to make it readable (Dmitry)
- Few nits (Dmitry)
Changes in v10:
- Fix white spaces in a separate patch (Dmitry)
Changes in v11:
- Define a macro for dspp flush selection (Marijn)
- Few nits (Marijn)
Changes in v12:
- Minor comments (reorder macros and a condition) (Marijn)
