EDAC: Check for GHES preference in the chipset-specific EDAC drivers

Browse source 
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.
