[PATCH 0/3] Fix and improve USB3 support on Armada 37xx

Hi,

The first patch fixes a wrong IRQ number present since the
introduction of the device tree for this SoC.

The second and the third ones improve the USB3 representation
following the add of the clock support on Armada 37xx and the gpio
expander on Armada 3720 DB.

Thanks,

Gregory

IRQ number for xhci controller was wrong, fix it.

Now that clocks are available provide a clock resource for xhci node.

Now that the gpio expander is present in the dts, use it to add an USB3
PHY using one of these gpio as a regulator.
