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.

The main function of the twl6040 is to provide audio on OMAP4+ platforms.
Since the ASoC codec driver can work without the pdata we can register the
child to load the codec driver whenever the twl6040 MFD driver is loaded.

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()

ab8500-i2c is used as core code to register the ab8500 device.
After allocating ab8500 memory, it immediately calls into
ab8500-core where the real initialisation takes place. This
patch moves all core registration and memory allocation into
the true ab8500-core file and removes ab8500-i2c completely.

The modern idiom is to use irq_domain to allocate interrupts. This is
useful partly to allow further infrastructure to be based on the domains
and partly because it makes it much easier to allocate virtual interrupts
to devices as we don't need to allocate a contiguous range of interrupt
numbers.

Convert the wm831x driver over to this infrastructure, using a legacy
IRQ mapping if an irq_base is specified in platform data and otherwise
using a linear mapping, always registering the interrupts even if they
won't ever be used. Only boards which need to use the GPIOs as
interrupts should need to use an irq_base.

This means that we can't use the MFD irq_base management since the
unless we're using an explicit irq_base from platform data we can't rely
on a linear mapping of interrupts.  Instead we need to map things via
the irq_domain - provide a conveniencem function wm831x_irq() to save a
small amount of typing when doing so. Looking at this I couldn't clearly
see anything the MFD core could do to make this nicer.

Since we're not supporting device tree yet there's no meaningful
advantage if we don't do this conversion in one, the fact that the
interrupt resources are used for repeated IP blocks makes accessor
functions for the irq_domain more trouble to do than they're worth.
