binman: Add CBI overlay section of fmap
The CBI section could be enabled if it's imported in the project.
The CBI section will be filled with 0xFF in binary. The size and
offset could be overridden with device tree config in chip or
program or project.
Add properties named 'preserve' and 'fill-byte' to flash layout
node to support new CBI section properties.
