drm/imx: parallel-display: add legacy bridge Kconfig dependency

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.

drm/imx: ldb: switch to imx_legacy_bridge / drm_bridge_connector

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.

Revert "drm: Make drivers depends on DRM_DW_HDMI"

This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helper
code should always be selected by the driver that needs it, for the
convenience of the final user configuring a kernel.

The user who configures a kernel should not need to know which helpers
are needed for the driver he is interested in. Making a driver depend
on helper code means that the user needs to know which helpers to enable
first, which is very user-unfriendly.

drm: Make drivers depends on DRM_DW_HDMI

DRM_DW_HDMI has a number of dependencies that might not be enabled.
However, drivers were used to selecting it while not enforcing the
DRM_DW_HDMI dependencies.

This could result in Kconfig warnings (and further build breakages) such
as:

Kconfig warnings: (for reference only)
WARNING: unmet direct dependencies detected for DRM_DW_HDMI
Depends on [n]: HAS_IOMEM [=y] && DRM [=m] && DRM_BRIDGE [=y] && DRM_DISPLAY_HELPER [=n]

drm: Drop ARCH_MULTIPLATFORM from dependencies

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

into its own subdirectory to make the separation more clear.
