Revert "acpi: Bump FADT to revision 6"
This reverts commit c8b0f31ca1b6cae993736d47d919080b6c186c6f. Bumping the FADT table version from 3 to 6 causes Windows 10 to BSOD with an ACPI BIOS error or simply fail to boot on multiple platforms (Haswell, Broadwell, Braswell, Skylake). Revert until the issue can be properly identified and corrected.
