x86/acpi: Update MADT table version

Update the MADT table version to sync with the FADT table version.
All current coreboot FADT tables are set to ACPI_FADT_REV_ACPI_3_0
and the MADT should be set to match.

This error was found by running FWTS:
FAILED [MEDIUM] SPECMADTFADTRevisions: Test 2, MADT revision is not in sync with
the FADT revision; MADT 1 expects FADT 3.0 but found 4.0 instead.

The test report is a little confusing due to the revision index
not matching the ACPI spec versions.

BUG=b:112476331
TEST-Run FWTS
