The PWM backlight still supports passing a enable GPIO line as platform data using the legacy <linux/gpio.h> API. It turns out that ever board using this mechanism except one is pass .enable_gpio = -1. So we drop all these cargo-culted -1's from all instances of this platform data in the kernel. The remaning board, Palm TC, is converted to pass a machine descriptior table with the "enable" GPIO instead, and delete the platform data entry for enable_gpio and the code handling it and things should work smoothly with the new API.
