VIA Nano: Add support for VIA Nano CPUs

Add code to do the following for the VIA Nano CPUs
    - Update microcode
    - Set maximum frequency
    - Initialize power states
    - Set up cache

Attempting to change the voltage or frequency of the CPU without
    applying the microcode update will hang the CPU, so we only do
    transitions if we can verify the microcode has been updated.

The microcode is updated directly from CBFS. No microcode is
    included in ramstage. The microcode is not included in this
    commit.

To get the microcode, run bios_extract on the manufacturer supplied
    BIOS, and look for the file marked "P6 Microcode". Include this
    file in CBFS.
    You can have the build system include this file automatically by
    selecting Expert Mode, then look under
    'Chipset' -> 'Include CPU microcode in CBFS' ->
    Include external microcode file (check)
    'Path and filename of CPU microcode' should contain the location of
    the microcode file previously extracted.
