Fix some existing bugs that prevent the driver from working properly
and adapt the platform-specific code to support the UMS9230 SoC.
Signed-off-by: Otto Pflüger <otto.pflueger@abscue.de>

Changes in v3:
- Split the device tree clock name change into a separate patch
- Add Fixes tags for all patches that fix something
- Open-code drm_simple_encoder_init()
- Use devm_drm_bridge_alloc for bridge allocation
- To account for the new atomic commit order, do not rely on the DPU
being initialized during pre_enable
- Correct remaining uses of drm_gem_dma/drm_fb_dma to use the custom
buffer object type
- Return the sgtable instead of 0 in sprd_gem_object_get_sgtable when
the IOMMU is not in use
- Reword some commit messages
- Link to v2: https://lore.kernel.org/r/20250722-ums9230-drm-v2-0-05427...
Changes in v2:
- Fix device tree binding syntax
- Use more descriptive clock names
- Keep IOMMU handle in DPU node and make the driver handle this instead
(otherwise the binding turns out to be incorrect for newer hardware)
- Remove all accesses to IOMMU registers from the DPU driver (after
observing that sharkl3 can also use sprd_iommu, I concluded that they
should not be needed at all)
- Fix container_of macros in sprd_dsi.h
- Link to v1: https://lore.kernel.org/r/20250719-ums9230-drm-v1-0-e4344...
