sensors: Remove TurboAllowedSensor

The TurboAllowed sensor is already mapped to
/xyz/openbmc_project/control/host0/turbo_allowed
(Reference: the phosphor-ipmi-sensor-inventory-mrw-config/config.yaml file).
Remove it from the deprecated /org/openbmc/sensors path.

Tested: Powered on a Witherspoon to the Host OS without errors.
