According to the reference manual of the i.MX25 the host controller uses an
offset of 0x200 not 0x400 as was specified in the resources for mxc_usbh2.

i.MX25's OTG has the same USBCTRL registers than i.MX35 so reuse
most of the i.MX35's defines.

As the kernel contains a copy of the GPL anyhow just get rid of the address
specification instead of fixing it.

- The SIC mask is only 2bits wide, not 4
- MX31_OTG_PM_BIT and MX31_H1_PM_BIT use negative logic
- clear MX31_H1_DT_BIT and MX31_H2_DT_BIT so that they can be cleared,
  not only set.
- return -EINVAL if called with an invalid controller number

The Freescale MX27 and MX31 SoCs have a EHCI controller onboard.
The controller is capable of USB on the go. This patch adds
a driver to support all three of them.

Users have to pass details about serial interface configuration in the
platform data.

The USB OTG core used here is the ARC core, so the driver should
be renamed and probably be merged with ehci-fsl.c eventually.
