CONFIG_HOTPLUG is going away as an option so __devexit_p is no longer
needed.

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.
