Kconfig: Add option for microcode filenames
Hardcoding the microcode filenames into the makefiles is great when
the microcode is in the blobs directory. When the microcode isn't
posted to the blobs directory, we need some method of supplying the
microcode binary into the build. This can of course be done manually
after the build has completed, as can be done with everything that
we're including in the ROM image. Instead of making life hard for
everyone though, let's just add a way to specify where the microcode
rom comes from.
