Most of the subdevices for the WM8350 code are registered in the same
fashion so factor out the code to do the initial registration.

The WM8350 features six DCDC convertors (four buck and two boost), four
LDO voltage regulators and two constant current sinks. This driver adds
support for these through the regulator API.
This driver was written by Liam Girdwood with updates for submission
from Mark Brown.

The WM8350 has an interrupt line to the CPU which is shared by the
devices on the CPU. This patch adds support for the interrupt
controller within the WM8350 which identifies which identifies the
interrupt cause. In common with other similar chips this is done
outside the standard interrupt framework due to the need to access
the interrupt controller over an interrupt-driven bus.
This code was all originally written by Liam Girdwood with updates for
submission by me.

Some functions of the WM8350 require board-specific initialisation on
startup. Provide a callback to the WM8350 driver in platform data
for platforms to use to configure the chip. Use of a callback allows
platforms to control the ordering of initialisation which can be
important.

The WM8350 is an integrated audio and power management subsystem
intended for use as the primary PMIC in mobile multimedia applications.
The WM8350 can be controlled via either I2C or SPI - the control
interface is provided by a separate module in order to allow greatest
flexibility in configuring the kernel.
This driver was originally written by Liam Girdwood and has since been
updated to current kernel APIs and split up for submission by me. All
the heavy lifting here was done by Liam.
