Enable the microcode feature so that the microcode version is shown with the
'cpu detail' command.

8bf08b4207 x86: Add some more common MSR indexes
Many of the model-specific indexes are common to several Intel CPUs. Add
some more common ones, and remove them from the ivybridge-specific header
file.

709b1902d2 x86: ivybridge: Set up the thermal target correctly
This uses a non-existent node at present. It should use the first CPU node.
The referenced property does not exist (the correct value is the default of
0), but this allows the follow-on init to complete.

9d156b5725 x86: ivybridge: Move CPU init code into the driver
Use the CPU driver's probe() method to perform the CPU init. This will happen
automatically when the first CPU is probed.

bba22a97a7 x86: ivybridge: Use common CPU init code
The existing ivybridge code predates the normal multi-core CPU init, and
it is not used. Remove it and add CPU nodes to the device tree so that all
four CPUs are set up. Also enable the 'cpu' command.

63d54a6705 x86: Clean up lapic codes
This commit cleans up the lapic codes:
- Delete arch/x86/include/asm/lapic_def.h, and move register and bit
  defines into arch/x86/include/asm/lapic.h
- Use MSR defines from msr-index.h in enable_lapic() and disable_lapic()
- Remove unnecessary stuff like NEED_LAPIC, X86_GOOD_APIC and
  CONFIG_AP_IN_SIPI_WAIT
- Move struct x86_cpu_priv defines to asm/arch-ivybridge/bd82x6x.h, as
  it is not apic related and only used by ivybridge
- Fix coding convention issues

45b5a37836 x86: Add multi-processor init
Most modern x86 CPUs include more than one CPU core. The OS normally requires
that these 'Application Processors' (APs) be brought up by the boot loader.
Add the required support to U-Boot to init additional APs.
