usb: chipidea: usbmisc: add post handling and errata fix for mx25

This adds a post handling routine which is called after
ci13xxx_add_device was called. The first user is the mx25, which has to
disable the external-vbus-divider after the udc has started.

 another set of line-too-long and void pointer casting errors]
