It seems, that since Linux 4.18-rc2 ci_hdrc depends on ulpi.

usb: chipidea: Always build ULPI code
Commit
03e6275ae381 ("usb: chipidea: Fix ULPI on imx51") causes a kernel
hang on imx51 systems that use the ULPI interface and do not select the
CONFIG_USB_CHIPIDEA_ULPI option.
In order to avoid such potential misuse, let's always build the
chipidea ULPI code into the final ci_hdrc object.
