I think the problem is that ehci-platform driver gets loaded instead of ehci-omap.

In the DT node we have compatible ids for both. e.g. for omap4.dtsi

                        usbhsehci: ehci@4a064c00 {
                                compatible = "ti,ehci-omap", "usb-ehci";
                                reg = <0x4a064c00 0x400>;
                                interrupt-parent = <&gic>;
                                interrupts = <GIC_SPI 77 IRQ_TYPE_LEVEL_HIGH>;
                        };

Shouldn't ehci-omap driver be getting a higher priority than usb-ehci?

A quick fix would be to eliminate "usb-ehci" from the DT node of all failing platforms.
