USB: renesas_usbhs: drop unused legacy-phy support
Drop support for legacy phys for rcar2 which hasn't been used with a mainline kernel since commit 9080b8dc761a ("ARM: OMAP2+: Remove legacy usb-host.c platform init code"). Specifically, since that commit usb_get_phy_dev() have always returned -ENODEV and consequently this code has not been used. Note that the legacy-phy API is still being used in gadget mode to bind the peripheral controller.
