Compiling the Intel microcode package results in a microcode.bin and a microcode-64.bin. As we can decide based on the subtarget which should be used, we'll only split the required .bin file with iucode-tool.
Instead of using the large microcode.bin/microcode-64.bin, the splitted ucode files (separate for CPU families) will be installed. The microcodes are updated from preinit - that's the earliest place where we can do it.
