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.
