nfp: add nfp_cpp_area_size() accessor
Allow users outside of core reading area sizes. This was not needed
previously because whatever entity created the area would usually know
what size it asked for. The nfp_rtsym_map() helper, however, will
allocate the area based on the size of an RT-symbol with given name.
