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

[Gregory CLEMENT]

Hi Tomáš Macholda,

> 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")
> Signed-off-by: Tomáš Macholda <tomas.macholda at nic.cz>

Applied on mvebu/dt64

Thanks,

Gregory
