LoongArch: Add FDT booting support from efi system table
Since commit 40cd01a9c324("efi/loongarch: libstub: remove dependency on
flattened DT"), we can parse the FDT from efi system table.
And now, LoongArch is coming to support booting with FDT, so we add the
relevant booting support as well as parameter parsing.
