syscon.h header uses struct device_node in functions' declarations
without declaring it. This causes compilation warnings like:

include/linux/mfd/syscon.h:20: warning: ‘struct device_node’
declared inside parameter list
include/linux/mfd/syscon.h:20: warning: its scope is only this
definition or declaration, which is probably not what you want

Fix it by adding a forward declaration of struct device_node.

For realistic systems the power management is controlled entirely via
runtime PM - if the device is not runtime suspended then the suspend
will abort without doing anything as functionality such as accessory
detection or audio bypass will require the device to be enabled while
if the device is runtime suspended it is already in the lowest power
state. This means that system suspend is redundant and can be removed
which avoids issues with attempting to double disable the regulators.

The Kconfig entry for DA9055 PMIC Support selects PMIC_DA9055. That was
probably inspired by the similar select statement in the entry for
DA9052/53 PMIC with I2C. But the DA9055 PMIC only comes in an I2C
variant and its driver doesn't need a separate Kconfig symbol for shared
code. In any case, this select can be dropped as PMIC_DA9055 doesn't
exist.

Palmas device have three different i2c addresses. The device creates
the two new dummy i2c clients for accessing the register by using
primary client adapter. This new dummy i2c client have their of_node
as NULL.

The dummy i2c client is used for registering interrupt and on this,
it creates irq domain handle. This created irq domain handle has
their of_node as NULL.

Now when any child of this device is registered through the DT as
follows:
         palmas: tps65913@58 {
         	::::::::::::::::::

         	#interrupt-cells = <2>;
                interrupt-controller;

                palmas_rtc {
                       compatible = "ti,palmas-rtc";
                       interrupt-parent = <&palmas>;
                       interrupts = <8 0>;
                };
                ::::::::::;;;
         };

And child driver (palam-rtc in this case) get their irq number as
	irq = platform_get_irq(pdev, 0);

The returned irq number is error in this case. The reason is that
the created irq_domain handle for the palmas interrupt does not have
valid node and so matching of node fails with palmas node.

Hence initialising the newly dummy created client->of_node with the
primary clients of_node so that irq_domain handle have proper of_node
for matching.

For Nokia RX-51 there is rx51_battery power_supply driver which reporting
