This commit fixes initialization of COMPHY on EspressoBin.
Commit 22f418935be4 ("phy: marvell: a3700: Use comphy_mux on Armada 37xx.") introduced usage of comphy_mux on Armada 37xx comphy driver. The lanes are defined in comphy_a3700.c as described in functional specification, that is: lane 0 is SGMII1 or USB3 lane 1 is PCIe or SGMII0 lane 2 is SATA or USB3
But the DTS for EspressoBin configures PCIe on lane 0 and USB3 on lane 1, which is wrong in the sense of the specification and doesn't work with the comphy_mux code, which is 2 years now (the aardvark driver causes synchronous abort in U-Boot).
I think armada-3720-db.dts requires the same fix?
