arm64: dts: marvell: armada-37xx: use 'usb2-phy' in USB3 controller's phy-names
Instead of the generic 'usb2-phy' name, the Armada 37xx device trees
are using a custom 'usb2-utmi-otg-phy' name for the USB2 PHY in the USB3
controller node. Since commit 53a2d95df836 ("usb: core: add phy notify
connect and disconnect"), this triggers a bug [1] in the USB core which
causes double use of the USB3 PHY.
Change the PHY name to 'usb2-phy' in the SoC and in the uDPU specific
dtsi files in order to avoid triggering the bug and also to keep the
names in line with the ones used by other platforms.
