staging: bcm2835-camera: Create struct mmal_es_format_local to mirror struct mmal_es_format
The struct struct mmal_es_format is passed between the firmware which has
pointers. A local version of mmal_es_format is also used.
Luckly, the two versions are always memberwise copied from each other
so simply have different structures for the local and msg versions.
