The Kconfig currently controlling compilation of this code is:
drivers/mfd/Kconfig:config MFD_WM831X_I2C
drivers/mfd/Kconfig: bool "Wolfson Microelectronics WM831x/2x PMICs with I2C"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
Since module_init was not in use by this code, the init ordering
remains unchanged with this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

Add NULL check before dereferencing pointer of_id in order to avoid
a potential NULL pointer dereference.

Add the basic ability to register the device through device tree, more
work is needed to get each individual sub-driver functioning correctly
but this is enough to get the device to probe from device tree.

i2c_driver does not need to set an owner because i2c_register_driver()
will set it.

In systems where there is no hardware signal from the processor to the
PMIC to initiate the final power off sequence we must initiate the
shutdown with a register write to the PMIC. Support such systems in the
driver. Since this may prevent a full shutdown of the system platform
data is used to enable the feature.

Factor out the register read/write code to use the register map API. We
still need some wm831x specific code and locking in place to check that
the user key is handled correctly but only on the write side, reads are
not affected by the key.

This saves us allocating an array on the stack, giving a meaningless
performance improvement and ensuring that if drivers ever do large writes
we'll not allocate large arrays on the stack.

In preparation for the addition of SPI support for the WM831x move the I2C
specific code into a separate file with a separate Kconfig option so the
I2C support can be excluded from the build.
Also update the 1133-EV1 PMIC module support for SMDK6410 to use the new
symbol.
