Replace the elaborate but awkward handling of FDT images using device paths and string PCDs initialized to 128 spaces with a simple scheme involving a set of builtin DTBs and a bit of runtime logic to select between them. This is sufficient for ordinary use, which makes it more suitable as reference code. Note that overriding the DTB presented to the OS can easily be done with a UEFI application that simply installs a new DTB image under the existing FDT configuration table GUID. For this module, this simply involves removing all code that is involved in deciding which platform we are running on, and for reasoning about FDT device paths.
