Subject: [PATCH v6 3/7] acpi: apei: remove the unused code

In current code logic, the two functions ghes_sea_add() and
ghes_sea_remove() are only called when CONFIG_ACPI_APEI_SEA
is defined. If not, it will return errors in the ghes_probe()
and not contiue. Hence, remove the unnecessary handling when
CONFIG_ACPI_APEI_SEI is not defined.

change since v5:
1. remove the SEI notification type handling, because the SEI is
   asynchronous exception and the address is not accurate. so
   not call memory_failure() to handle it.
