[PATCH] arm64: dts: marvell: armada-37xx: align 'phy-names' of EHCI node with DT schema

[Gabor Juhos]

According to the 'generic-ehci.yaml' schema, the name of the first phy
in an EHCI node must be "usb", however the 'usb at 5e000' node in the
'armada-37xx.dtsi' uses "usb2-utmi-host-phy" instead.

This causes dtbs_check warnings like the following ones:

  arch/arm64/boot/dts/marvell/armada-3720-atlas-v5.dtb: usb at 5e000 (marvell,armada-3700-ehci): phy-names:0: 'usb' was expected
      from schema $id: http://devicetree.org/schemas/usb/generic-ehci.yaml
  arch/arm64/boot/dts/marvell/armada-3720-db.dtb: usb at 5e000 (marvell,armada-3700-ehci): phy-names:0: 'usb' was expected
      from schema $id: http://devicetree.org/schemas/usb/generic-ehci.yaml
  arch/arm64/boot/dts/marvell/armada-3720-eDPU.dtb: usb at 5e000 (marvell,armada-3700-ehci): phy-names:0: 'usb' was expected
      from schema $id: http://devicetree.org/schemas/usb/generic-ehci.yaml
  ...

Use "usb" as a name for the phy to avoid the warnings.

No functional change, the USB interface works after the change:
