This adds core driver support for AB4500 mixed signal
multimedia & power management chip. This connects to U8500
on the SSP (pl022) and exports read/write functions for
the device to get access to this chip. This also registers
the client devices and sets the parent.

New MFD child to twl4030 MFD device.
Reason for the twl4030_codec MFD: the vibra control is actually in the codec
part of the twl4030. If both the vibra and the audio functionality is needed
from the twl4030 at the same time, than they need to control the codec power
and APLL at the same time without breaking the other driver.
Also these two has to be able to work without the need for the other driver.
This MFD device will be used by the drivers, which needs resources
from the twl4030 codec like audio and vibra.

When the sleep script is loaded before the wakeup script, there is a
chance that the system might go to sleep before the wakeup script
loading is completed. This will lead to a system that does not wakeup
and has been observed to cause non-booting boards.
Various options were considered to solve this problem, including
modification of the core twl4030 power code to be smart enough to
reorder the loading of the scripts. But it felt too over-engineered.
Hence this patch just warns the DPS script developer so that they may be
reordered in the board-code itself.

This adds the _interruptible suffix to the AB3100 accessor
functions on par with mutex_lock_interruptible() that's used
for blocking simultaneous calls to the AB3100 acessor functions.
Since these accesses are slow on a 100kHz I2C bus and may line
up waiting for the mutex, we need to handle interruption by
system shutdown or kill signals and may just as well denote that
in the function names.
