[PATCH] arm64: dts: cn913x: add device trees for COM Express boards

Add support for CN9130 and CN9131 COM Express Type 7 CPU module boards
by Marvell.
These boards differ from the existing CN913x DB boards by the type
of ethernet connection (RGMII), the type of voltage regulators
(not i2c expander based) and the USB phy (not UTMI based).
CN9131 COM Express board is basically CN9130 COM Express board
with an additional CP115 I/O co-processor, which in this case
provides an additional USB host controller on the board.
