Updated Intel CPU Microcode to 20200602 (prerelease) (bsc#1172466)

This update contains security mitigations for:

CVE-2020-0543: Fixed a side channel attack against special registers
 which could have resulted in leaking of read values to cores other than
 the one which called it. This attack is known as Special Register
 Buffer Data Sampling (SRBDS) or 'CrossTalk' (bsc#1154824).

CVE-2020-0548,CVE-2020-0549: Additional ucode updates were supplied to
 mitigate the Vector Register and L1D Eviction Sampling aka
 'CacheOutAttack' attacks. (bsc#1156353)
