The driver now uses the legacy bridge helper code but can be configured
to get built without it:
ERROR: modpost: "devm_imx_drm_legacy_bridge" [drivers/gpu/drm/imx/ipuv3/parallel-display.ko] undefined!
Add the required dependency, same as in the ldb driver.
Fixes: f94b9707a1c9 ("drm/imx: parallel-display: switch to imx_legacy_bridge / drm_bridge_connector")

Call drm_client_setup_with_color_mode() to run the kernel's default
client setup for DRM. Set fbdev_probe in struct drm_driver, so that
the client setup can start the common fbdev client.
v5:
- select DRM_CLIENT_SELECTION

When drm/bridge-connector was moved to DRM_DISPLAY_HELPER not all
users were updated. Add missing Kconfig selections.

Use the imx_legacy bridge driver instead of handlign display modes via
the connector node.
All existing usecases already support attaching using
the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag, while the imx_legacy bridge
doesn't support creating connector at all. Switch to
drm_bridge_connector at the same time.

Some of these dependencies used to be sensible when only a small part of
the platforms supported by ARCH=arm could be compiled together in a
single kernel image. Nowadays ARCH_MULTIPLATFORM is only used as a guard
for kernel options incompatible with a multiplatform image. See commit
84fc86360623 ("ARM: make ARCH_MULTIPLATFORM user-visible") for some more
details.

The IPUv3 and DCSS driver are two totally separate DRM drivers. Having
one of them live in the drivers/gpu/drm/imx toplevel directory and the
other one in the dcss/ subdirectory is confusing. Move the IPUv3 driver
into its own subdirectory to make the separation more clear.
