linux-firmware and CPU microcodes

Hello development folks,

while working on the linux-firmware update for Core Update 168 yesterday, I realised it comes with CPU microcodes for Intel and AMD as well (which kind of makes sense for a bundled conglomerate of firmware, I guess).

This means that either the CPU microcodes in linux-firmware or the dedicated LFS files for Intel and AMD microcode is redundant. Can we just drop the latter? Or did I overlook something?

Thanks, and best regards, Peter Müller
