This patch provides first-cut implementation of fw_dynamic firmware. As compared to fw_jump and fw_payload, the fw_dynamic obtains next address, next mode and OpenSBI options from struct fw_dynamic_info. The previous booting stage can create struct fw_dynamic_info in memory and pass address of struct fw_dynamic_info in 'a2' register. Also, the struct fw_dynamic_info has versioning as well so changes to the struct fw_dynamic_info can be done in a backward compatible manner.
