Add a structure which defines the information that is needed for executing capsule updates on a platform. Some information in the structure like the dfu string is used for making the update process more robust while some information like the per platform image GUIDs is used for fixing issues. Initialise this structure in the board file, and use the information for the capsule updates. Signed-off-by: Sughosh Ganu <sughosh.ganu@linaro.org>
