ls1028a has a reset module that includes reboot, reset control word, and
service processor control.

Add platform specific compatible string to fix the below warning.

syscon@1e60000: compatible: 'anyOf' conditional failed, one must be fixed:
        ['syscon'] is too short
        'syscon' is not one of ['al,alpine-sysfabric-service', ...]
