[0/6] Add Armada 3700 COMPHY support

Message

Hello,

This series adds a new driver to support Armada 3700 COMPHY IP.
The series has been tested on an ESPRESSObin with SATA, PCIe
and USB3 host. For this purpose, patch 1 enumerates the SATA PHY
mode. The SGMII PHY mode that is supported by the IP has been written
(uses SMC calls anyway) but could not be tested on this platform.

Three series will follow to add PHY support (or at least a PHY nodes
in the A3700/ESPRESSObin device trees) to the MVEBU AHCI driver, the
Aardvark PCI controller driver and the MVEBU xHCI driver. All this is
needed in order to achieve suspend to RAM on this platform.

Thanks,
Miquèl
