A platform_driver does not need to set an owner, it will be populated by the
driver core.

Some gpio implementations return interesting values for gpio_get_value when
the value is not 0 - as seen on a imx6sl board. Therefore do not use the
value returned from gpio_get_value directly but simply check for 0 or not 0.

The driver core clears the driver data to NULL after device_release or on
probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d
(device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is
not needed to manually clear the device driver data to NULL.

Context of gpio_charger_get_property is sleepable so we should
use gpio_set_value_cansleep instead of gpio_set_value.
It will remove WARN_ON incase of using gpio from i2c-to-gpio
expander like pca953x.

This patch converts the drivers in drivers/power/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

request_any_context_irq() returns a negative value on failure.
On success, it returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED.

Gpio charger should notify if the gpio state had changed
during suspend. This will send a CHANGED event each time
the system resumes, ensuring a plug/unplug of the charger
is not missed.

This patch fixes a potential race between the irq handler and the probe
and remove functions.
The irq should not be requested before the chargers power_supply has been
registered and has to be freed before the power_supply is unregistered,
otherwise it is possible that the irq fires while the power_supply is not
initialized yet or has already been freed.
While we are at it replace request_irq with request_any_context_irq.
