Combine both generic and arch-specific parts of microcode into a
single module (arch-specific parts are config-dependent).
Also while we are at it, move arch-specific parts from microcode.h
into their respective arch-specific .c files.

this is a rework of the microcode splitup in tip/x86/microcode
(1) I think this new interface is cleaner (look at the changes
in 'struct microcode_ops' in microcode.h);
(2) it's -64 lines of code;

This is the 1st patch in the series. Here the aim was to avoid any
significant changes, logically-wise.
So it's mainly about generic interface refactoring: e.g. make
microcode_{intel,amd}.c more about arch-specific details and less
about policies like make-sure-we-run-on-a-target-cpu
(no more set_cpus_allowed_ptr() here) and generic synchronization (no
more microcode_mutex here).
All in all, more line have been deleted than added.

Refactored code by introducing a two-module solution.
There is one general module in which vendor specific modules can hook into.
However, that is exclusive, there is only one vendor specific module
allowed at a time. A CPU vendor check makes sure only the correct
module for the underlying system gets called.
Functinally in terms of patch loading itself there are no changes. This
refactoring provides a basis for future implementations of other vendors'
patch loaders.

Refactoring with the goal of having one general module and separate
vendor specific modules that hook into the general one.
Microcode_ops is a function pointer structure in which vendor
specific modules will enter all functions that differ between
vendors and that need to be accessed from the general module.

Renamed common structures to vendor specific naming scheme
so other vendors will be able to use the same naming
convention.

This structure will be later used by other modules as well and
needs therfore to be moved out to a header file.

Intel specific microcode declarations have been moved to a seperate header file.
There are no code changes to the code itself and no side effects to other parts.
