Commit dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES in apci_init()") introduced a bug that ghes_edac_register() would be invoked before edac_init(). Because at that time, the bus "edac" hasn't been even registered, this created sysfs /devices/mc0 instead of /sys/devices/system/edac/mc/mc0 on an Ampere eMag server.
The solution is modularizing the ghes_edac driver.
I tested the cases as follows: 1. build test with ghes_edac built-in and module on Aarch64 2. build test with ghes_edac built-in and module on x86_64 3. boot test with ghes_edac built-in and module on Aarch64 4. modprobe and -r for multiple times on Aarch64.
