intel/skylake: Switch FADT to ACPI version 3.0
On Apollo Lake it was discovered that our current FADT implementation is valid for ACPI version 3.0 but misses fields for ACPI version 5.0. We run into booting issues with Windows 10 using version 5 in the FADT header. In commit 2b8552f49bc3a7d0290f96a84b573669de396011 (intel/apollolake: Switch FADT to ACPI version 3.0) we go back to version 3 for Apollo Lake. Skylake is now the last platform that uses version 5 in FADT header.
