[U-Boot] [PATCH V3] usb:ci_udc: Remove ULPI setting for i.MX OTG controller

[Peng Fan]

From: "Ye.Li" <B37916 at freescale.com>

All the i.MX6, i.MX23 and i.MX28 OTG controllers only support UTMI
interface. Set to ULPI is not correct, even the controller will
reject this setting in PORTSC register.

Hi Marek,
 In V2: https://patchwork.ozlabs.org/patch/541663/
 The reason still use DBG, but not change to debug, is that the driver
 use DBG for debugging and error handling usage.
 So In this patch, I still keep DBG. If you think, it better to switch
 to use function debug, I can write another patch to convert all the
 DBGs to debug for ci_udc driver.

Regards,
Peng.

Changes since v2:
 - Correct code indent.
Changes since v1:
 - Add error handling for udc probe
