[PATCH 06/11] MXS: Add small registration glue for ci13xxx_udc

[Chen Peter-B29397]

> 
> +config USB_CI13XXX_MXS

> +	  i.MX SoC has chipidea USB controller.  This driver uses
> +	  ci13xxx_udc core.
> +	  This driver depends on OTG driver for PHY initialization,
> +	  clock management, powering up VBUS, and power management.
> +	  This driver is not supported on boards like trout which
> +	  has an external PHY.
> +
> +	  Say "y" to link the driver statically, or "m" to build a
> +	  dynamically linked module called "ci13xxx_msm" and force all
> +	  gadget drivers to also be dynamically linked.

cil3xxx_msm????? should be cil3xxx_mxs?
