ARM: pxa: Initialize PWM backlight enable_gpio field
The GPIO API defines 0 as being a valid GPIO number, so this field needs to be initialized explicitly. A special case is the Palm Tungsten|C board. Since it doesn't use any quirks that would require the existing .init() or .exit() hooks it can simply use the new enable_gpio field. Signed-off-by: Thierry Reding <treding@nvidia.com>
