backlight: remove ADX backlight device support
Support for the Avionic Design Xanthos backlight device got added in commit 3b96ea9ef8 ("backlight: Add support for the Avionic Design Xanthos backlight device."). That support depends on ARCH_PXA_ADX. The code that should have provided that Kconfig symbol never got submitted. It has never been possible to even build this driver. Remove it.
