[RFCv2 16/16] Makefile: Drop linux/kconfig.h from config.h

[Tom Rini]

From: Simon Glass <sjg at chromium.org>

This header always included by the build system (see UBOOTINCLUDE) except
when building tools, so is unnecessary. Drop it and update the
documentation in the common.h header.

Tools generally should not make use of the board config, but a few do.
Update the Atmel pmecc tool to cope with this.
