POST: move CONFIG_POST to Makefiles
Introduce the new logical option CONFIG_HAS_POST which is set when the
platform has CONFIG_POST set. Use CONFIG_HAS_POST in the post/ Makefiles
to determine should the POST libs be compiled for the selected target
platform, or not.
To avoid breaking u-boot linking process, the empty post/libpost.a file is
created for platforms which do not have POSTs.
