acpi_idle: delete bogus data from cpuidle_state.power_usage
The mW data in this field comes from AML _CST, which was typed in by a BIOS writer, and is thus considered unreliable. Linux does not use it for making any decisions. We do display it in sysfs where somebody might read it and assume it is meaningful, so delete it. Signed-off-by: Len Brown <len.brown@intel.com>
