soc/intel/cannonlake: Add device Ids for new CFL SKUs support

- Add CPU, MCH & IGD IDs for new Coffeelake SKUs

- Add PCH, LPC, SPI IDs for CNP-H PCH CM246 & C246

- Make some minor alignments & naming corrections to align with the rest

TEST= build, boot to both Linux & windows OS on CFL H & S platforms
and verified all the device Id's in serial console logs.
