[PATCH 4/4] startup: set barebox_main in data section

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

By initializing barebox_main in start_barebox(), we preclude changing
barebox_main before start_barebox() is called.

This can be useful, at least in sandbox. Therefore, let's initialize
barebox_main statically.
