Paolo Bonzini acd727e7cb acpi-dsdt: procedurally generate _PRT
This replaces the _PRT constant with a method that computes it.

The problem is that the DSDT+SSDT have grown from 2.0 to 2.1,
enough to cross the 8k barrier (we align the ACPI tables to 4k
before putting them in fw_cfg).  This causes problems with
migration and the pc-i440fx-2.0 machine type.

The solution to the problem is to hardcode 64k as the limit,
but this doesn't solve the bug with pc-i440fx-2.0.  The fix will be
for QEMU 2.1 to use exactly the same size as QEMU 2.0 for the
ACPI tables.  First, however, we must make the actual AML
equal or smaller; to do this, rewrite _PRT in a way that saves
over 1k of bytecode.
