bsps/powerpc: Fix small data area section

Browse Source 
Fix small data area in case no fixed size is desired.  Rename
bsp_section_set_sdata_sbss_size into bsp_section_small_data_area_size
since this symbol reflects the overall small data area size (including
space for libdl).  Do not use bsp_section_sbss_size before definition in
linker command file.  Add new symbols to <bsp/linker-symbols.h>.

Update #3687.
