Commit cf7c93cdd755 "usb: ehci: Implement V2P mapping" introduced usage of virt_to_phys() in ehci-hcd.
Since there was no implementation of virt_to_phys() for ARC compilation of the ehci-generic driver failed.
This change adds virt_to_phys() stub for ARC so now USB driver for AXS101 board could be built again.
