Certain BIOS versions of Intel SoCs with In-Band ECC capability
(e.g. Arizona Beach SoCs) may fuse off some memory controllers,
causing the current igen6_edac driver to mistakenly register these
absent controllers with the EDAC core.

Patch 1: Get the igen6_edac driver to skip absent memory controllers,
         preventing erroneous registration with the EDAC core.

Patch 2: Add EDAC support for Intel Arizona Beach SoCs (for network computing).
         This patch depends on Patch 1.

Patch 3: Add EDAC support for Intel Amston Lake SoCs (for edge computing).

Qiuxu Zhuo (3):
  EDAC/igen6: Skip the absent memory controllers
  EDAC/igen6: Add Intel Arizona Beach SoCs support
  EDAC/igen6: Add Intel Amston Lake SoCs support
