prog_loading: add region_device representing memory

One can remove the struct buffer_area and use the region_device
    embedded in the struct prog to represent the in-memory loaded
    program. Do this by introducing a addrspace_32bit mem_region_device
    that can have region_device operations performed on it. The
    addrspace_32bit name was chosen to make it explicit that 32-bits
    of address space is supported at the max.
