[PATCH 13/19] include: <asm-generic/bug.h>: implement ASSERT()

[Sascha Hauer]

ASSERT() is a statement commonly used by other projects. This patch adds
an implementation for it.

It is normally compiled away and can be enabled with
CONFIG_BUG_ON_DATA_CORRUPTION.

While ASSERT() is usually written in lowercase letters, use uppercase
letters for barebox as we have a function hook in the reset controller
core that uses lowercase letters.
