This driver has not been converted to Driver Model, and it is an obstacle to migrate other block device drivers. Remove it for now.
The UniPhier SoCs already use a DM-based EHCI driver, so now ARCH_UNIPHIER can select DM_USB.
These two changes must be done atomically because removing the legacy driver causes a build error.
