ti,system-power-controller is more or less the standard way of
indicating that the PMIC is the system wide power controller and hence
may be used to switch off the system. Almost ALL TI PMIC drivers and
many Maxim PMIC drivers follow the same style.

So support 'ti,system-power-controller' in addition to the usual
'ti,use_poweroff' to indicate that the PMIC instance has control for
switching off the system.

The GPBR block provides a set of battery-backed registers that can be used
to save data which need to be kept when the system is powered down and
VDD-core is maintained by an external battery.

A typical usage is the RTT block (when used as an RTC) which needs one of
those registers to save the current time.

Some oscillators can be turned off during off-idle saving few

These settings are based on the "Recommended Sleep Sequences for
the Zoom Platform".

The settings assume most of the regulators are under control of
Linux, and twl4030 only cuts off VDD1 and VDD2 during off-idle as
Linux cannot do it.

For any board specific changes to these, let's patch them in as
changes to the generic data in the follow-up patches. This keeps
the board specific changes small.

Note that this does not consider the twl5030 errata 27 and 28.
That can be added later on after it has been tested. For more
information about errata 27 and 28.

The twl4030 PMIC needs to be configured properly for things like
warm reset and deeper idle states so the PMIC manages the regulators
properly based on the hardware triggers from the SoC. Earlier
we have configured twl4030 using platform data, but we want to
do it for device tree based booting also.

In some cases configuring twl4030 is needed for things to work.
For example, when rebooting an OMAP3530 at 125 MHz, it hangs.
With this patch, TWL4030 will be reset when a warm reset occures,
and OMAP3530 does not hang on reboot.

Let's add device tree support and configure things for warm reset
as the default when compatible = "ti,twl4030-power". More
complicated configurations can be added to the driver based on
other compatible flags.

Note we now also make the pdata const like it should be.
This allows use it for match->data with the device tree
related functions.
