cheza: Wrap FMAP sections with calibration data in RO_PRESERVE section 

The Cheza board contains a couple of non-standard FMAP sections that
contain per-board calibration data. When flashing new firmware to the
board, care should be taken to copy these sections over so that all
features can still function correctly afterwards. This patch wraps a new
RO_PRESERVE FMAP section around these sections to make them easier to
preserve as a group.
