usb: mv_udc: Rename to ci_udc
The mv_udc is not marvell-specific anymore. The mv_udc is used to drive generic ChipIdea CI13xxx series OTG cores, so rename the driver to ci_udc instead. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Eric Nelson <eric.nelson@boundarydevices.com> Cc: Stefano Babic <sbabic@denx.de>
