Mark Brown 48c98b1bb8 Input: samsung-keypad - implement runtime power management support 
When runtime power management is enabled put the Samsung keypad driver
into suspend mode with wakeups disabled whenever the device is open but
a key is not actually been pressed. As well as saving a trivial amount of
power this will support the use of SoC wide idle modes which put the entire
device into a retention mode and use explicit wakeup sources to exit.

Since not all of the interrupt controllers used with the driver support
set_irq_wake() (though they all do the right thing) and there's a nasty
WARN() when we disable wake after failing to enable it keep track of the
current wake status from runtime PM and only disable wake if we managed
to enable it; I'm not entirely sure why this doesn't affect the existing
uses of the API in the driver.

System suspend is unaffected as the driver core will runtime resume any
suspended devices prior to system suspend.
