Shouldn't DT preserve pdev name and id to allow platform_match to work?

Actually, I'm planning to merge OF_DEV_AUXDATA_ID().  I was hoping to
avoid it but there was enough hard-to-solve-quickly problems that I've
relented.

Adding the match table is not hard-to-solve though, so I'm not
relenting on that point.  :-)
