  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)
