usb: ehci-mx6: Fix bus enumeration for iMX7 SoCs
This fixes the issues with calculation of controller indexes in
ehci_usb_bind() for iMX7, as USB controllers on iMX7 SoCs aren't
placed next to each other, and their addresses incremented by 0x10000.
Example of USB nodes for iMX7S/D:
usbotg1: usb@30b10000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b10000 0x200>;
^^^^^^^^^^
....
usbotg2: usb@30b20000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b20000 0x200>;
^^^^^^^^^^
....
usbh: usb@30b30000 {
compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
reg = <0x30b30000 0x200>;
^^^^^^^^^^
....
Which was leading to usb enumeration issues:
Colibri iMX7 # usb start
starting USB...
Bus usb@30b10000: USB EHCI 1.00
Bus usb@30b20000: probe failed, error -22
scanning bus usb@30b10000 for devices... 1 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
