At udc, it uses otg_set_peripheral, which depends on otg. OTG depends on
both host and device are enabled.

In fact, we don't need to use otg_set_peripheral at udc if all usb part
is in chipidea driver, but currently, msm also uses chipidea/udc.c, and
its otg and host is out of chipidea/

I am working on suspend/resume, low power mode and wakeup on chipidea driver.
After that, I will work on it.
