soc/intel/cse: Add config to enable PSR data backup for CSE Lite SKU
Intel Platform Service Record (PSR) provides on-platform persistent and tamper resistant ledgers and counters. Key events captured within the Intel PSR Event Ledger, e.g., Chassis Intrusion Detection, can be observed over the life cycle of the platform to help assess confidence. Counters for platform S0 operational use and power state transitions can be assessed to aid in the determination of general wear or correlations of other platform events when determining platform decommission plans (repurpose, resell, recycle). PSR data is created and stored in CSE data partition. In platforms that employ CSE Lite SKU firmware, a firmware downgrade involves clearing of CSE data partition which results in PSR data being lost. CSE Lite SKU firmware supports a command to backup PSR data before initiating a firmware downgrade. Add a config to support this PSR data backup flow.
