x86/microcode_intel_early.c: Early update ucode on Intel's CPU
Implementation of early update ucode on Intel's CPU.
load_ucode_intel_bsp() scans ucode in initrd image file which is a cpio format
ucode followed by ordinary initrd image file. The binary ucode file is stored
in kernel/x86/microcode/GenuineIntel.bin in the cpio data. All ucode
patches with the same model as BSP are saved in memory. A matching ucode patch
is updated on BSP.
load_ucode_intel_ap() reads saved ucoded patches and updates ucode on AP.
