usb: ci_udc: terminate ep0 INs with a zlp when required Sometimes, a zero-length packet is required at the end of an IN transaction so that the host knows the device is done sending data. Enhance ci_udc to send a zlp when necessary. See the comments for more details. Signed-off-by: Stephen Warren <swarren@nvidia.com>
