Cover letter [PATCH 0/3] efi/arm: refactor DT EFI param parsing
In preparation for another arrival (RISC-V), do some janitorial work on the FDT param parsing code for EFI as well. The code sits in an #ifdef block in efi.c, which is usually a good indicator that it should be moved into its own source file. Then, we simplify the DT handling, by switching to the FDT library, instead of going through the more high level early OF enumeration code, which in our case will be doing libfdt calls under the hood as well, as EFI on ARM specifically uses *flattened* DT. (note that the EFI stub for ARM uses libfdt as well to populate the DT properties that we read back here)
