Upcoming PG2 devices will use SR2.x SoCs and will therefore need separate device trees. Prepare for that by factoring out common bits that will be shared across both generations. At this chance, drop a link to the product homepage to in the top-level dts files. Also fix a typo in my email address in some headers.
