USB: phy: drop legacy board-file support
The legacy interface for associating controllers with phys from board
files and platform code has been unused since commit 9080b8dc761a ("ARM:
OMAP2+: Remove legacy usb-host.c platform init code"). Since then, all
calls to usb_get_phy_dev() and its devres version have been returning
-ENODEV.
Now that the final calls to these functions have been removed, we can
drop this legacy lookup interface altogether.
