RAS/CEC: Add CONFIG_RAS_CEC_DEBUG and move CEC debug features there
The pfn and array files in (debugfs)/ras/cec are intended for debugging
the CEC code itself. They are not needed on production systems, so the
default setting for this CONFIG option is "n".
[ bp: Have it with less ifdeffery by using IS_ENABLED(). ]
