USB: core: hcd: drop support for legacy phys

Browse Source 
Drop support for looking up and initialising legacy phys in USB core,
something which hasn't been used by a mainline kernel since commit
9080b8dc76 ("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.
