hw/riscv: Return the end address of the loaded firmware

Browse source 
Instead of returning the unused entry address from riscv_load_firmware()
instead return the end address. Also return the end address from
riscv_find_and_load_firmware().

This tells the caller if a firmware was loaded and how big it is. This
can be used to determine the load address of the next image (usually the
kernel).
