Add printer support to puc(4) driver.

      -	Move isa/ppc* to sys/dev/ppc (repo-copy)
      -	Add an attachment method to ppc for puc
      -	In puc we need to walk the chain of parents.
Still to do, is to make ppc(4) & puc(4) work on other platforms.  Testers
wanted.

PR:		38372 (in spirit done differently)
Verified by:	Make universe (if I messed up a platform please fix)
