x86: clean up apic->acpi_madt_oem_check methods
Impact: refactor code x86 subarchitectures each defined a "acpi_madt_oem_check()" method, which could be an inline function, or an extern, or a static function, and which was also the name of a genapic field. Untangle this namespace spaghetti by setting ->acpi_madt_oem_check() to NULL on those subarchitectures that have no detection quirks, and rename the other ones (summit, es7000) that do. Also change default_acpi_madt_oem_check() to handle NULL entries, and clean its control flow up as well. Signed-off-by: Ingo Molnar <mingo@elte.hu>
