GHES still fills in the CPER record, but the parsing and logging logic is
shared with the new DeviceTree provider so I pulled those helpers into the
estatus core. Both providers already call into the same notifier chain and
memory-pool helpers; this patch just moves the generic CPER walking routines
next to the rest of the common code so the DT path doesn’t have to grow its
own copy. If you’d prefer a different file layout or naming to make that
intent clearer, I’m happy to adjust.
