arc: Add virt_to_phys() stub
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.
