USB: musb: omap2430: drop non-DT support
Drop support for non-DT systems, which hasn't been used by 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 when looking up a legacy phy, something which in turn would have led to the init callback returning -EPROBE_DEFER indefinitely.
