[PATCH mvebu-dt64] arm64: dts: turris-mox: fix usb3 phys

After commit 00e6d608fe80b0f6 ("arm64: dts: marvell: armada-37xx: swap
PHYs' order in USB3 controller node") swapped USB3 PHY order, USB
initialization breaks on Turris MOX.

This regression was exposed by commit 91ddf6f722084383 ("phy: marvell:
mvebu-a3700-utmi: fix incorrect USB2_PHY_CTRL register access") which
made USB2 devices not work at all.

Fix the issue by explicitly adding all USB3 PHYs and PHY names to
Turris MOX device-tree.

Fixes: 7109d817db2e ("arm64: dts: marvell: add DTS for Turris Mox")
