Tomasz Maciej Nowak 546fced2a2 x86: add intel microcode entries to grub config
Create initrd enries for x86 images, that'll load intel microcode as
early as possible. To achieve that the test module for grub is enabled
which provides shell-like conditionals. Also restrict the late load of
microcode to AMD processors.
