During my research I found that some of the requirements for the memory buffers for MFC v6+ devices were blindly copied from the previous (v5) version and simply turned out to be excessive. The relaxed requirements are applied by the recent patches to the MFC driver and the driver is now fully functional even without the reserved memory blocks for all v6+ variants. This patch removes those reserved memory nodes from all boards having MFC v6+ hardware block.
