Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

- * struct regulator_ops - regulator operations.
- *
- * @enable: Configure the regulator as enabled.
- * @disable: Configure the regulator as disabled.
- * @is_enabled: Return 1 if the regulator is enabled, 0 if not.
- * May also return negative errno.
- *
- * @set_voltage: Set the voltage for the regulator within the range specified.
- * The driver should select the voltage closest to min_uV.
- * @set_voltage_sel: Set the voltage for the regulator using the specified
- * selector.
- * @get_voltage: Return the currently configured voltage for the regulator.
- * @get_voltage_sel: Return the currently configured voltage selector for the
- * regulator.
- * @list_voltage: Return one of the supported voltages, in microvolts; zero
- * if the selector indicates a voltage that is unusable on this system;
- * or negative errno. Selectors range from zero to one less than
- * regulator_desc.n_voltages. Voltages may be reported in any order.
- *
- * @set_current_limit: Configure a limit for a current-limited regulator.
- * @get_current_limit: Get the configured limit for a current-limited regulator.
- *
- * @set_mode: Set the configured operating mode for the regulator.
- * @get_mode: Get the configured operating mode for the regulator.
- * @get_status: Return actual (not as-configured) status of regulator, as a
- * REGULATOR_STATUS value (or negative errno)
- * @get_optimum_mode: Get the most efficient operating mode for the regulator
- * when running with the specified parameters.
- *
- * @enable_time: Time taken for the regulator voltage output voltage to
- * stabilise after being enabled, in microseconds.
- * @set_voltage_time_sel: Time taken for the regulator voltage output voltage
- * to stabilise after being set to a new value, in microseconds.
- * The function provides the from and to voltage selector, the
- * function should return the worst case.
- *
- * @set_suspend_voltage: Set the voltage for the regulator when the system
- * is suspended.
- * @set_suspend_enable: Mark the regulator as enabled when the system is
- * suspended.
- * @set_suspend_disable: Mark the regulator as disabled when the system is
- * suspended.
- * @set_suspend_mode: Set the operating mode for the regulator when the
- * system is suspended.
- *
- * This struct describes regulator operations which can be implemented by
- * regulator chip drivers.
