Sometimes the contents of a partition are compressed. Add a property to express this and define the algorithm used.

Signed-off-by: Simon Glass sjg@chromium.org ---

Changes in v4: - Add an example

Changes in v3: - Just add a compression property for now

Changes in v2: - Use "binman" for compatible instead of "u-boot,binman" - Significantly rework the patch - Use make dt_binding_check DT_SCHEMA_FILES=Documentation/../partitions
