Bspec uses ..P for "<platform> PCH", when it acknowledges the existence
of said PCH (see eg. CNP,ICP,TGP). JSP is not among that select crowd
however, neither really is MCC (although it is mentioned by name in the
JSL section).

I kinda want to nuke the JSP and MCC types entirely. I believe we should
be able to treat them as just ICP and TGP variants respectively. But
theres's still a bit of work left to do before we can get there.
