Device tree based probing support for the core twl6040 driver. Child
devices will be created as MFD devices:
- ASoC codec is always created
- Vibra child is only created if the vibra section present in the DT blob.

Use irq_alloc_descs() to get the IRQ number range dynamically instead of
the hardwired use if pdata->irq_base.
The twl6040 only provides interrupts for it's internal components which
means that it is not working as an IRQ expander type of device.
The client drivers will receive their interrupt numbers as resource which
is configured based on the received IRQ range we got from irq_alloc_descs()

No functional change, just to make the code a bit more uniform and
remove wrapped lines.

In order to operate correctly twl6040 needs correct
interrupt configuration.
The slave drivers (vibra, and ASoC codec) will refuse
to probe, if the interrupt configuration is not correct.
In this way some checks can be removed from the code.

TWL6040 IC provides analog high-end audio codec functions for
handset applications. It contains several audio analog inputs
and outputs as well as vibrator support. It's connected to the
host processor via PDM interface for audio data communication.
The audio modules are controlled by internal registers that
can be accessed by I2C and PDM interface.
TWL6040 MFD will be registered as a child of TWL-CORE, and will
have two children of its own: twl6040-codec and twl6040-vibra.
This driver is based on TWL4030 and WM8350 MFD drivers.
