ENGR00236031 MX6 USB :Change default USB H1 and OTG driver load order

In current linux BSP USB H1 driver default load before otg driver load,
which cause USBx not match the ehci controller number. like bellow:

root@freescale /sys/devices/platform/fsl-ehci.0$ ls
driver     modalias   pools      power      subsystem  uevent     usb2
root@freescale /sys/devices/platform/fsl-ehci.1$ ls
driver     modalias   pools      power      subsystem  uevent     usb1
