AMD NPT 0Fh cpus use 6 bit VID codes. Successive codes with msb 0
describe 25mV decrements, while those with msb 1 describe 12.5mV
decrements. Existing hwmon-vid.c is correct only for codes with msb 0;
add support for the codes with msb 1.

cpu_data is currently an array defined using NR_CPUS.  This means that
we overallocate since we will rarely really use maximum configured cpus.
When NR_CPU count is raised to 4096 the size of cpu_data becomes
3,145,728 bytes.

These changes were adopted from the sparc64 (and ia64) code.  An
additional field was added to cpuinfo_x86 to be a non-ambiguous cpu
index.  This corresponds to the index into a cpumask_t as well as the
per_cpu index.  It's used in various places like show_cpuinfo().

cpu_data is defined to be the boot_cpu_data structure for the NON-SMP
case.

If we cannot guess which VRM version the CPU uses, we set it to 0 and
log it. So we shouldn't spam the log each time vid_from_reg() is
later called with vrm 0.

This patch adds the VIA CENTAUR CPUs to detection table.
Table was updated to treat future Intel x86 CPUs as VRD10.
Stepping field was added, because some VIA CPUs have
different VRM specs across stepping. I changed the vrm type
to u8 because all drivers use u8 anyway.

I see very little reason why vid_from_reg is inlined. It is not
exactly short, its parameters are seldom known in advance, and it is
never called in speed critical areas. Uninlining it should cause
little performance loss if any, and saves a signficant space as well
as compilation time.

As suggested by Alexey Dobriyan, I am leaving vid_to_reg inline for now,
as it is short and has a single user so far.

The only part left in i2c-sensor is the VRM/VRD/VID handling code.
This is in no way related to i2c, so it doesn't belong there. Move
the code to hwmon, where it belongs.

Note that not all hardware monitoring drivers do VRM/VRD/VID
operations, so less drivers depend on hwmon-vid than there were
depending on i2c-sensor.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
