power_status: Removed of the scaling of charge_full_design

Initial assumptions about battery health were flawed. Multiple
errors have been found in the process used to identify the
typical battery health on deployed devices. Further investigation
has not shown any devices that need the scaling factors.

The battery FSI targets specified a target of 97% within 50
cycles as measured by the smart batteries self reported full
charge capacity (FCC) / design capacity (DC). ECs on older
platforms were scaling down the FCC ratio to 98% of it's value
so any platform with a typical battery usage of .97*.98=95% was
actually meeting our targets. All platforms are hitting this
threshold on the typical values and the remaining regressions
can be attributed to storage and user behavior of dogfood
devices.
