Add a method to the mkeficapsule bintool to generate empty capsules. These are capsules needed for the FWU A/B update feature.
Signed-off-by: Sughosh Ganu sughosh.ganu@linaro.org --- Changes since V1: * Use a single boolean value to indicate the generation of either of accept/revert capsule. * Move the parameters added to the list on the same line in a couple of places.
