Enable DT based probing of the vibra driver.

Example of dts section to load the twl6040-vibra driver:
twl6040: twl6040@4b {
	...
	twl6040_vibra: twl6040@1 {
		compatible = "ti,twl6040-vibra";
		interrupts = <4>;
		vddvibl-supply = <&vbat>;
		vddvibr-supply = <&vbat>;
		vibldrv_res = <8>;
		vibrdrv_res = <3>;
		viblmotor_res = <10>;
		vibrmotor_res = <10>;
	};
};

Complete the separation of the twl6040 from the twl core since
it is a separate chip, not part of the twl6030 PMIC.

Make the needed Kconfig changes for the depending drivers at the
same time to avoid breaking the kernel build (vibra, ASoC components).

The VIBSELL/R bit in the VIBCTLL/R register tells the source of the data,
which is going to be used to drive the attached motor(s).
Do not allow effect execution if any of the channels are set to receive
audio data.

The bits within the two control registers (for left and right channel)
are identical.
Use common names for the bits acros the two register.
Also add the missing definition for the path selection bit.

Fix warning from Geert's build summary emails by changing "if" to
"ifdef". Thsi should fix the following:

drivers/input/misc/twl6040-vibra.c:231:5: warning: "CONFIG_PM_SLEEP" is not defined

Builds cleanly with CONFIG_PM_SLEEP enabled or disabled.

The twl6040_request_irq/free_irq inline functions are going
to be removed, so replace them with direct calls.
The irq number is provided by the core driver via resource.

Add twl6040_vibra as a child of MFD device twl6040_codec. This
implementation covers the PCM-to-PWM mode of TWL6040 vibrator
module.
