[PATCH 09/16] boot: split off bootarg API into new bootargs.h header

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

In preparation for adding new functions to the flexible bootarg support
that are not used at boot-time, factor out the bootargs support,
so new code need not include the whole boot.h header.
