nfp: add nfp_cpp_area_size() accessor

Browse source 
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.
