When booting via platform code the AB8500 platform data is now passed
in though the DB8500. However, if pdata_size is not set it will not be
subsequently passed onto subordinate devices. This patch correctly
populates pdata_size.

This was introduced in commit
876989d (mfd: Add device tree probe support for mc13xxx)
for spi and later while introducing support for i2c copied to the i2c
driver.
Modifying driver details is very strange, for example probing an
mc13892 device (instantiated via dt) removes the driver's ability to
handle (traditionally probed) mc13783 devices in this case.
I'm not aware of any problems that make this hack necessary and if
there were some, they'd have to be fixed in the spi/i2c core, not in
a driver.

device_init_wakeup uses the dev_name() of the device to set the
name of the wakeup_source which appears in
/sys/kernel/debug/wakeup_sources.
For a platform device, that name is not set until platform_device_add
calls dev_set_name.
So the call to device_init_wakeup() must be after the call to
platform_device_add().
Making this change causes correct names to appear in the

mfd: Initial support for Wolfson Arizona platform and WM5102 devices
The Wolfson Arizona platform is used to provide common register
interface to a series of low power audio hub CODECs, starting with the
WM5102. Since the features of these devices work over a range of
subsystems an MFD core driver is provided to instantiate the subdevices
and arbitrate access between them.
As the new regmap wake IRQ functionality is used as part of the driver
it is incorporated as a dependency.
As the AB8500 is a subordinate MFD device to the DB8500-PRCMU,
for consistency and a better 1:1 depiction of how the hardware
is laid out, it is a good idea to register it in the same way
as we do for the other MFD child devices. In order for us to do
this successfully we have to pass AB8500's platform data when
registering the DB8500-PRCMU from platform code.
Also solves this issue:
