Doesn't this introduce a new warning with simple-bus.yaml? These
devices shouldn't be under an AXI bus which should require a
unit-address.

All the sft-eth* nodes have the same problem:
axi at 600000000: sfp-eth63: {'compatible': ['sff,sfp'], 'i2c-bus':
[[91]], 'tx-disable-gpios': [[87, 31, 0, 1]], 'rate-select0-gpios':
[[87, 31, 1, 0]], 'los-gpios': [[88, 31, 0, 0]], 'mod-def0-gpios':
[[88, 31, 1, 1]], 'tx-fault-gpios': [[88, 31, 2, 0]], 'phandle':
[[78]]} should not be valid under {'type': 'object'}
