[pbsd-mg2] Commit NetBSD/hpcmips codes

["TAKEMURA, Shin" <takemura@netbsd.org>]

Greetings,

I'm working on NetBSD/hpcmips which is a port for embedded MIPS 
CPU machines like a PDA. (i.e. MIPS based Windows CE machines.)
And now I'm ready to marge source codes and commit into -current
repositry.

I will add many new files and modify 15 files below which are shared
by MIPS base systems. Most of modifications are enclosed by 
#ifdef and I belive it has no side-effect.

If there is no problem, I will commit in a few days.
