We have a lot of defconfigs for ARM9 AT91 boards, that we want to get
rid off after migrating the boards to at91_multi_defconfig.
Thanks to a temporarily donated Calao USB-A9G20 by Wolfram, we start by
switching the Calao boards to DT.
This is not yet a complete replacement:
- We use the legacy NAND driver instead of the newly backported driver
that Linux uses with the hardware, presumably without issues
- OHCI hangs during probe, so it's disabled for now
- A barebox with comparative functionality to the non-DT version
exceeds the 256K partition size
These can be resolved separately though, so add here first DT support.

Revert "mtd: nand: drop DT support in legacy driver"
ARM: at91: add SDRAMC driver for memory detection
ARM: at91: at91sam9_rst: add DT support for at91sam9260
ARM: at91: sam9260: don't build non-DT device support when unneeded
ARM: at91: add first DT support for Calao usb/tny boards
