[PATCH] bootchooser: export bootchooser_entry_boot function

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

When migrating a board to use bootchooser instead of a custom boot
handler, it can be useful to add an intermediate boot target that
decides whether to use bootchooser or the old boot target it replaces.

Make expressing this straight-forward in C by exporting
bootchooser_entry_boot(), so it can be called from the intermediate boot
target's struct bootentry::boot function.
