EDAC: Check for GHES preference in the chipset-specific EDAC drivers
Call ghes_get_devices() to check whether ghes_edac should be used on the platform where it is preferred over the corresponding chipset-specific EDAC driver. Unlike the existing edac_get_owner() check, the ghes_get_devices() check works independent to the module_init ordering.
