ENGR00315894-44 imx6:USB: Update EHCI driver for OTG lines compatibility
To be compatible with more USB otg lines which has micro port B to
connect imx6 OTG port when imx6 working at host mode, remove the
checking for the OTG ID with the init type. Only use the init type
for the power and controller initialization.
Use same EHCI register base address for various imx6 platform.
