Currently, neoverse_rd is hosted under the "css" directory. However,
"css" directory is more relevant for hosting css definitions and
corresponding sources. Since neoverse_rd hosts source and header for css
and soc, move neoverse_rd from css to board folder. Consolidate common
sources and headers under neoverse_rd/common. Additionally, group RD-V1,
RD-V1-MC, RD-N2, RD-N1-Edgex2 and SGI-575 within neoverse_rd/platform.
