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

Peter,

As Tejun mentioned, there is no difference between having a "private"
workqueue created with alloc_workqueue() with default parameters and
using system-wide workqueue. Therefore please use system-wide one. If
your use shows that you indeed need high-priority workqueue it can be
added later.

I have replaced the singlethreaded wq with the call suggested by Tejun:
https://lkml.org/lkml/2011/6/17/99

If this is a problem, I can rework this, and remove the code, which is not 
going to be needed, when the system_wq is in use, but I would like to keep the 
alloc_workqueue way, since it is going to be easier for us to experiment with 
parameters, if we face with issues.
 

Otherwise:

        Acked-by: Dmitry Torokhov [off-list ref]

Please feel free to merge this code with the rest of TWL6040 patches
(presumably throgh Samuel's MFD tree).

Thank you,
Péter
