Series drm/display: Convert helpers Kconfig symbols to depends on | expand

Commit Message

All the helpers Kconfig symbols so far have relied on drivers selecting
them, and that's what most drivers did.

However, this creates an issue nowadays when helpers depend on each
other, and select doesn't transitively select a dependency dependencies.

Depends on doesn't have that limitation though, so let's convert those
symbols to be dependable and use depends on between them too.
