Warner Losh 2a829b00f4 Now that we have the resource allocation code in current, the kludge
to try to allocate things on my parent can be taken out.  It duplicates code.

Also, add comment about why the power state stuff is here (type 2
devices don't participate in the power state save/restore due to
larger Bx issues).
