Armada 38x USB-2.0 PHYs are similar to Armada 8K (CP110) and can be
supported by the same driver with small differences.
Add new compatible string for armada-38x variant of utmi phy.
Then add descriptions and names for two additional register definitions
that may be specified instead of a syscon phandle.
