[PATCH 01/12] include: common.h: move barebox startup functions into separate header

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

Symbols exclusively defined in common.h are a problem, because other
headers that require them will need to include a lot of extra baggage,
which in the worst case can lead to cyclic dependencies and in every
case leads to longer compile times.

In preparation for turning common.h into containing only #include lines,
let's move the barebox boot stage stuff into a separate header.
