hv: vacpi: add fadt table support

Browse Source 
Add FADT table support to support guest S5 setting.

According to ACPI 6.3 Spec, OSPM must ignored the DSDT and FACS fields if them're zero.
However, Linux kernel seems not to abide by the protocol, it will check DSDT still.
So add an empty DSDT to meet it.
