[PATCH 3/6] x86/microcode: Remove modularization leftovers

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

Remove the remaining module functionality leftovers. Make
"dis_ucode_ldr" an early_param and make it static again. Drop module
aliases, autoloading table, description, etc.

Bump version number, while at it.
