Add rules to compile dts files into dtb files using the device tree compiler (dtc). A platform can specify the DTS file to compile using the platform-dtb-y variable. The flattened device tree binary file to be used for building the final polatform firmware can be specified using the new FW_PAYLOAD_FDT firmware configuration option to point to the automatically compiled FDT file. Using the existing FW_PAYLOAD_FDT_PATH configuration option is still possible and will take precedence over the FW_PAYLOAD_FDT definition. Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com>
