Stefan Berger 2803917a09 tpm2: Switch to uncompressed lists and adapt un/marshal functions
Switch the implementation to uncompressed lists (from now on it must
remain uncompressed lists forever) and adapt functions who marshal
and unmarshal arrays that are affected by this switch:

- PERSISTENT_DATA.ppList
- PERSISTENT_DATA.auditCommands
