This update for microcode_ctl fixes the following issues:

Added microcode_amd_fam17h.bin (bsc#1068032 CVE-2017-5715)

This new firmware disables branch prediction on AMD family 17h processor.

Also the CPU microcode for Intel Haswell-X, Skylake-X and Broadwell-X
chipsets was updated to report both branch prediction control via CPUID
flag and ability to control branch prediction via an MSR register.

This update is part of a mitigation for a branch predictor based
information disclosure attack, and needs additional code in the Linux
Kernel to be active (bsc#1068032 CVE-2017-5715)
