soc/intel/xeon_sp/skx: Clean up FADT

Both `acpi_fill_fadt` and `soc_fill_fadt` set many FADT fields. Since
the latter runs later, the values programmed in it overwrite any other
values. Drop unused assignments and consolidate everything in a single
function. Use `acpi_fill_fadt` as it is mandatory (no weak definition).
