A check for a valid plat->sysctrl was introduced in:
2377e52 mfd: ab8500-sysctrl: Error check clean up
but the driver works just fine even without that initialization data,
and enforcing it breaks existing platforms for no reason.
This patch removes the check and let the driver go ahead with probe.

AB8500 sysctrl driver implements a pm_power_off handler, but that is
currently not registered until a specific platform data field is
enabled.
This patch drops the platform data field and always registers
ab8500_power_off if no other pm_power_off handler was defined before,
and also introduces the necessary cleanup code in the driver's remove
function.

The driver requires sysctrl_dev to be set at probe, as it's used by
other driver functions. This was dropped by mistake in:
2377e52 mfd: ab8500-sysctrl: Error check clean up
making all driver functions fail.

The abx500-clk driver is initiated at arch_initcall level. Moreover it
is relying on the ab8500-sysctrl API to be available. Therefore move
ab8500-sysctrl to arch_initcall level as well. The device is already
added before the abx500 clk device, thus it will be probed before as
well, which is exactly what we want.

It's possible to supply a string to provide a reason for
triggering a restart. In this case our reason is to enter
charging-only mode, as a charger was found to be present.

When a charger is connected, we usually want AB8500 based systems to
reboot into charging-only mode. However, if the battery type cannot
be identified this would be futile, so we'll just shut the system
down instead.

The kernel allows us to specify a function call-back which will be
invoked when a system power-off request has been received. Here we
provide one which is to be used when shutting down AB8500 based
platforms.

Now the MFD API is Device Tree aware we can use it for platform
registration again, even when booting with DT enabled. To aid in
Device Node pointer allocation we provide each cell with the
associative compatible string.

This patch ensures probing of the ab8500-sysctrl driver during a DT
enabled boot, so long as the associated nodes are present in the
Device Tree binary.

This moves all the header files related to the abx500 family into
a common include directory below mfd. From now on we place any
subchip header in that directory. Headers previously in e.g.
<linux/mfd/ab8500/gpio.h> get prefixed and are now e.g.
<linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface
remains in <linux/mfd/abx500.h>.

With the pending module.h cleanup, these files will fail to compile,
unless they explicitly call out the include of this file.

This adds a pretty straight-forward system control driver for the
AB8500. This driver will be used from the core platform, e.g the
clock tree implementation in the machine code, and is by nature
singleton.
There are a few simple functions to read, write, set and clear
registers so that the machine code can control its own foundation.
