intel/apollolake: Switch FADT to ACPI version 3.0
The current implementation of the FADT structure is only ACPI 3.0 compliant.
Setting the version to ACPI 5.0 results in a corrupt FADT. Linux seems
to be able to deal with it but Windows 10 hangs in a really early stage
without any notification to the user.
If ACPI 5.0 is mandatory, the FADT structure needs to be adjusted to
match the specification. Therefore the members sleep_ctl and sleep_stat
needs to be added to FADT structure.
