[PATCH 1/2] x86/microcode: Remove the driver announcement and version

[Borislav Petkov]

From: "Borislav Petkov (AMD)" <bp@xxxxxxxxx>

First of all, the print is useless. The driver will either load and say
which microcode revision the machine has or issue an error.

Then, the version number is meaningless and actively confusing, as Yazen
mentioned recently: when a subset of patches are backported to a distro
kernel, one can't assume the driver version is the same as the upstream
one. And besides, the version number of the loader hasn't been used and
incremented for a long time. So drop it.
