USB: phy: drop unused legacy controller-phy bind helper
Drop the unused legacy usb_bind_phy() helper whose last user was removed in 2016 when OMAP moved to device-tree boot (9080b8dc761a ("ARM: OMAP2+: Remove legacy usb-host.c platform init code")). Note that this means that for the last couple of years the phy_bind_list has been empty (when using mainline kernels) and that consequently all phy lookups using the usb_get_phy_dev() interface have failed with -ENODEV. This helper along with its current users will be removed by follow-on patches. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
