I have just realized that this cannot be dropped until my series "ARM:
dts: meson: fix UART device-tree schema validation" [0] is merged

This part is still needed as long as above series is not merged yet.
If we remove this then earlycon will stop working on the 32-bit SoCs
unless [0] is merged.

All other code below - except the of_device_id entry - can still be
removed since meson8.dtsi and meson8b.dtsi are using the non-legacy
clocks already.

Sorry for only noticing this now.


Best regards,
Martin
