[RFC] Add UPL FDT handoff

This adds another handoff that is basically the same as coreboot tables.
The only real difference is that it uses the devicetree format to
transfer the information to payload.
This handoff is inspired by the UPL (universal payload) specification.

Tested: start q35 qemu with coreinfo as payload and see that console
still works and the devicetree is printed by coreboot.
