Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

expo: Plumb in textlines to a scene

are displayed correctly. Provide a way to have a border around the
textline, with the internal part being the same colour as the
background. This looks more natural.

expo: Set up the width and height of objects

Provide a way to set the full dimensions of objects, i.e. including the
width and height.

For menus, calculate the bounding box of all objects in the menu. Set all
labels to be the same size, so that highlighting works correct, once
implemented.

expo: Calculate text bounding-box correctly

Rather than estimating, measure the text accurately, using the new
vidconsole feature. This allows accurate placement of objects.

expo: Use flags for objects

We currently have just a 'hide' property for each object. In preparation
for adding more properties, convert the struct to use a flags value,
instead of individual booleans. This is more extensible.

expo: Add width and height to objects

At present objects only have a position so it is not possible to determine
the amount of space they take up on the display.

Add width and height properties, using a struct to keep all the dimensions
together.

For now this is not used. Future work will set up these new properties.

expo: Allow setting the start of the dynamic-ID range

Provide a way to set this value so that it is easy to separate the
statically allocated IDs (generated by the caller) from those
generated dynamically by expo itself.

bootstd: Add a separate log category for expo

This feature is different enough from bootstd that it probably deserves
its own log category. It cannot use a uclass since it is not a device.

Add a new category.

expo: Avoid automatically arranging the scene

This should ideally be done once after all scene changes have been made.
Require an explicit call when everything is ready.

Always arrange after a key it sent, just for convenience.

expo: Store the console in the expo

Rather than finding this each time, keep a pointer to it. This simplifies
the code a little.

expo: Convert to using a string ID for the scene title

This is easier to deal with if it uses the existing string handling,
since we will be able to use translations, etc. in the future.

Update it to use an ID instead of a string.

expo: Add support for scenes

A scene is a single screen within an expo. It is possible to move between
scenes but only one can be displayed at once.

Add a basic implementation.
