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(). ] Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Borislav Petkov <bp@suse.de>
