Use per-core mutex for XSCOM for P8 errata.
See HW822317. The HMER register in P8 is not implemented to
handle multi-threaded XSCOM properly, so we need to move the
XSCOM mutex from per-thread to per-core. Also, there is an
issue where the 'done' bit can come on 1 cycle before the error
indicators, so need to potentially read the HMER a second time.
