The bootph-all flag was introduced in dt-schema
(dtschema/schemas/bootph.yaml) to define node usage across
different boot phases.

To ensure SD boot, timer, gpio, syscfg, clock and uart nodes need to be
present in all boot stages, so add missing bootph-all phase flag
to these nodes to support SD boot.

I resent a v3 ASAP.
