x86: microcode_amd: remove (wrong) chipset deivce ID checks

Browse source 
Impact: remove dead/incorrect code

Currently there is no chipset specific ucode. The checks are incorrect
anyway (e.g. pci device IDs are 16 bit and not 8 bit).

Thus I remove the stuff for the time being and will reintroduce it if
it's foreseeable that it is really needed.
