EDAC/ghes: Make ghes_edac a proper module
Commit
dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES in apci_init()")
introduced a bug leading to ghes_edac_register() to be invoked before
edac_init(). Because at that time the bus "edac" hadn't been even
registered, this created sysfs nodes as /devices/mc0 instead of
/sys/devices/system/edac/mc/mc0 on an Ampere eMag server.
Fix this by turning ghes_edac into a proper module.
The list of GHES devices returned is not protected from being modified
concurrently but it is pretty static as it gets created only during GHES
init and latter is not a module so...
[ bp: Massage. ]
