Discover hardware via device tree

Instead of mixing PCDs and libraries to describe the hardware, we could parse device trees and leverage the driver binding model in UEFI.

ACPI tables (and devices) can be generated this way as well.

This would also make it possible to build the firmware once, then just pack it alongside a DTB and other data (such as the splash logo) for each platform.

This sounds interesting
