Can't you call phy_bind() from usb_musb_init() with the default
values automatically when usb_musb_init() is passed NULL?

That way you don't have to patch every board-*.c file with the
same lines, and don't need to include <linux/phy/phy.h> in each
board-*.c file.

Here usb_musb_init() gets called with musb_board_data, so
keeping the phy_bind() in the board-4430sdp.c can then override
the default in usb_musb_init().
