ACPI: fix early DSDT dmi check warnings on ia64

WARNING: at drivers/firmware/dmi_scan.c:423 dmi_matches+0x70/0x160()
dmi check: not initialized yet.

This is caused by commit aa2110c
(ACPI: add boot option acpi=copy_dsdt to fix corrupt DSDT).
DMI is not initialized yet in acpi_early_init on ia64.

The DSDT DMI check table is x86 specific, so make it empty on other archs.
And this fixes the warnings on ia64.
