acpi: make default DSDT optional
Since commit f7e4dd6c18ccfbaf6cd2f5eaaed2b77cabc8a406 QEMU loads its
own copy of DSDT, so let's not build in PIIX. This makes building in
the DSDT an option, default to on (built-in). If no one complains for a
while, we'll be able to switch it off and then maybe remove altogether.
