power: supply: gpio-charger: Make gpios optional
While strongly recommended, not all devices have a gpio to detect if the charger is connected. This moves the 'gpios' from required to optional section. This also modifies error handling for the GPIO a bit: We no longer fallback to pdata, if a GPIO is specified using GPIO descriptor tables. This is a bit cleaner and does not have any real impact: There are only two mainline pdata users (arm/mach-sa1100/collie.c, arm/mach-pxa/tosa.c) and none of them specify the GPIO via gpiod descriptor tables. Once both have been converted the driver's support for specifying GPIOs numbers in pdata will be dropped.
