Phil Dennis-Jordan 77af8a2b95 hw/i386: Use Rev3 FADT (ACPI 2.0) instead of Rev1 to improve guest OS support.
This updates the FADT generated for x86/64 machine types from Revision 1 to 3. (Based on ACPI standard 2.0 instead of 1.0) The intention is to expose the reset register information to guest operating systems which require it, specifically OS X/macOS. Revision 1 FADTs do not contain the fields relating to the reset register.

The new layout and contents remains backwards-compatible with operating systems which only support ACPI 1.0, as the existing fields are not modified by this change, as the 64-bit and 32-bit variants are allowed to co-exist according to the ACPI 2.0 standard. No regressions became apparent in tests with a range of Windows (XP-10) and Linux versions.

The BIOS tables test suite's FADT checksum test has also been updated to reflect the new FADT layout and content.
