Subject: [PATCH] sys-firmware/intel-microcode: Bump

Ebuild changes:
===============
- Based on Intel's microcode tarball from 2018-04-25.

- Added 210+ additional microcode updates (for production, no beta release!),
  which are signed by Intel and publicly available but are not distributed
  via Intel's microcode tarball for marketing/product phase out reasons.
  You can prevent the usage of these microcode updates and stick with
  content from Intel's official release tarball via new "vanilla"
  USE flag.

- Blacklisted microcode 0x000604f1 aka 06-4f-01 aka CPUID 406F1 which
  requires a newer microcode loader in kernel which is only available
  in kernel >=4.14.34.
  It is blacklisted because loading via older loader could crash the
  system. A news item with instructions will follow.

Closes: https://github.com/gentoo/gentoo/pull/8532
Bug: https://bugs.gentoo.org/654638
Package-Manager: Portage-2.3.38, Repoman-2.3.9
