[PULL 07/28] docs/interop/firmware.json: add new enum FirmwareFormat

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

From: Thomas Weißschuh <thomas.weissschuh@linutronix.de>

Only a small subset of all blockdev drivers make sense for firmware
images. Introduce and use a new enum to represent this.

This also reduces the dependency on firmware.json from the global qapi
definitions.

Claim "Since: 3.0" for the new enum, because that's correct for its
members, and the members are what matters in the interface.
