OpenSBI is the default firmware in Qemu and has various firmware loading options. Currently, qemu loader uses fw_jump which has a compile time pre-defined address where fdt & kernel image must reside. This puts a constraint on image size of the Linux kernel depending on the fdt location and available memory. However, fw_dynamic allows the loader to specify the next stage location (i.e. Linux kernel/U-Boot) in memory and other configurable boot options available in OpenSBI. Add support for OpenSBI dynamic firmware loading support. This doesn't break existing setup and fw_jump will continue to work as it is. Any other firmware will continue to work without any issues as long as it doesn't expect anything specific from loader in "a2" register.
