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.
