x86/cpu/microcode: Zap changelog

It is useless at best and git history has it all detailed
anyway. Update copyright while at it.

- * 1.0 16 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Initial release.
- * 1.01 18 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Added read() support + cleanups.
- * 1.02 21 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Added 'device trimming' support. open(O_WRONLY) zeroes
- * and frees the saved copy of applied microcode.
- * 1.03 29 Feb 2000, Tigran Aivazian <tigran@sco.com>
- * Made to use devfs (/dev/cpu/microcode) + cleanups.
- * 1.04 06 Jun 2000, Simon Trimmer <simon@veritas.com>
- * Added misc device support (now uses both devfs and misc).
- * Added MICROCODE_IOCFREE ioctl to clear memory.
- * 1.05 09 Jun 2000, Simon Trimmer <simon@veritas.com>
- * Messages for error cases (non Intel & no suitable microcode).
- * 1.06 03 Aug 2000, Tigran Aivazian <tigran@veritas.com>
- * Removed ->release(). Removed exclusive open and status bitmap.
- * Added microcode_rwsem to serialize read()/write()/ioctl().
- * Removed global kernel lock usage.
- * 1.07 07 Sep 2000, Tigran Aivazian <tigran@veritas.com>
- * Write 0 to 0x8B msr and then cpuid before reading revision,
- * so that it works even if there were no update done by the
- * BIOS. Otherwise, reading from 0x8B gives junk (which happened
- * to be 0 on my machine which is why it worked even when I
- * disabled update by the BIOS)
- * Thanks to Eric W. Biederman <ebiederman@lnxi.com> for the fix.
- * 1.08 11 Dec 2000, Richard Schaal <richard.schaal@intel.com> and
- * Tigran Aivazian <tigran@veritas.com>
- * Intel Pentium 4 processor support and bugfixes.
- * 1.09 30 Oct 2001, Tigran Aivazian <tigran@veritas.com>
- * Bugfix for HT (Hyper-Threading) enabled processors
- * whereby processor resources are shared by all logical processors
- * in a single CPU package.
- * 1.10 28 Feb 2002 Asit K Mallick <asit.k.mallick@intel.com> and
- * Tigran Aivazian <tigran@veritas.com>,
- * Serialize updates as required on HT processors due to
- * speculative nature of implementation.
- * 1.11 22 Mar 2002 Tigran Aivazian <tigran@veritas.com>
- * Fix the panic when writing zero-length microcode chunk.
- * 1.12 29 Sep 2003 Nitin Kamble <nitin.a.kamble@intel.com>,
- * Jun Nakajima <jun.nakajima@intel.com>
- * Support for the microcode updates in the new format.
- * 1.13 10 Oct 2003 Tigran Aivazian <tigran@veritas.com>
- * Removed ->read() method and obsoleted MICROCODE_IOCFREE ioctl
- * because we no longer hold a copy of applied microcode
- * in kernel memory.
- * 1.14 25 Jun 2004 Tigran Aivazian <tigran@veritas.com>
- * Fix sigmatch() macro to handle old CPUs with pf == 0.
