Nitpicks and fixes from the discovery thread on adding PocketBeagle2 support
[1]. This does a lot of general setup required for the device, but these
modifications themselves aren't device specific. For those specifically
interested in PocketBeagle2 support and don't care about these details, my
development branch is public [2].
That first patch may provoke some opinions, but honestly if that warning was
still present I wouldn't have spent a week poking holes in both the EFI and LMB
allocations systems. Please let me know if there is a specific usecase that it
breaks though.

Randolph Sapp (5):
lmb: add LMB_FDT for fdt reserved regions
efi_dt_fixup: use fdtdec_get_bool
efi_selftest_memory: check for duplicates first
efi_mem_sort: skip unnecessary compare
