Bug Description
The Intel PCC interface http://
Fwts should probably do PCC table sanity checking with a new "pcc" test. Section 2.1 explains the table format quite clearly, so it should be relatively straight forward

Couple of notes:
In tests, evaluation of \_SB_.OSC, PCCH, PCCP (and _PSD) objects generally results in a SMI being called which is impossible to do from the user space context. Thus sanity checking the return data from these objects is impossible. The only other sanity checking that can be done is to search for the PCC header (see section 2.1) of the PCC spec and validate the structure.
1. If PCC objects exist, we should validate if the PCC header exists
2. If PCC header exists, should the PCC objects exist?
3. Validate PCC header fields
