lpc: Log LPC SYNC errors as unrecoverable ones for manufacturing
High volume of SYNC errors onto LPC bus cause degraded system
performance and are likely due to bad hardware present onto system.
Thus once LPC SYNC errors cross a certain threshold, OPAL should log
them onto BMC as unrecoverable errors in manufacturing mode. This
will help manufacturing screen bad parts, causing such errors.
