Krzysztof Kozlowski 0f78d6da0e arm64: dts: marvell: cn9130-db: drop wrong unit-addresses 
Top-level nodes, not being on MMIO bus, do not have "reg" properties and
should not have unit addresses.  Correct their name as well to match
"Generic node names" recommendation from Devicetree specification.
This also fixes dtc W=1 warnings:

  cn9130-db.dtsi:28.11-31.4: Warning (unique_unit_address_if_enabled): /memory@0: duplicate unit-address (also used in node /ap0_sd_vccq@0)
