soc/intel/broadwell: Set FADT `duty_offset` to 0
From ACPI specification, version 6.2 Errata A:
A `duty_width` value of 0 indicates that processor duty cycle is not
supported and the processor continuously runs at its base frequency.
Because Broadwell sets `duty_width` to 0, processor duty cycle is not
supported, and the value of `duty_offset` is ignored. For consistency
with Lynx Point, set `duty_offset` to 0.
