This branch is reducing in size for every release since most board-related
changes have started happening in devicetrees now. Still, we have some things
going on here.
* Renesas platforms are still adding a bit more legacy device support, something
that should trail off shortly as they move to full DT.
* We group most defconfig updates into this branch out of old habits
* Removal of legacy OMAP2 platforms over to DT continues, and a handful of old
code is being removed here.
