Currently save_microcode_in_initrd() is declared in vendor neutural
microcode.h file, but defined in vendor specific
microcode_intel_early.c file. Vendor abstract it out to
microcode_core_early.c with a wrapper function.Signed-off-by: Jacob Shin

For each CPU vendor that implements CPU microcode patching, there will
be a minimum family for which this is implemented. Verify this
minimum level of support.This can be done in the dispatch function or early in the application
functions. Doing the latter turned out to be somewhat awkward because
of the ineviable split between the BSP and the AP paths, and rather
than pushing deep into the application functions, do this in
the dispatch function.Reported-by: "Bryan O'Donoghue"

Define interfaces load_ucode_bsp() and load_ucode_ap() to load ucode on BSP and
AP in early boot time. These are generic interfaces. Internally they call
vendor specific implementations.Signed-off-by: Fenghua Yu
