x86/microcode/AMD: Add support for fam17h microcode loading
commit f4e9b7af0cd58dd039a0fb2cd67d57cea4889abf upstream.
The size for the Microcode Patch Block (MPB) for an AMD family 17h
processor is 3200 bytes. Add a #define for fam17h so that it does
not default to 2048 bytes and fail a microcode load/update.
