EDAC/i10nm: Skip the absent memory controllers
Some Sapphire Rapids workstations' absent memory controllers
still appear as PCIe devices that fool the i10nm_edac driver
and result in "shift exponent -66 is negative" call traces
from skx_get_dimm_info().
Skip the absent memory controllers to avoid the call traces.
