backlight: ktd2801: Fix unmet dependency on GPIOLIB

Browse Source 
LEDS_EXPRESSWIRE depends on GPIOLIB, so its selector, BACKLIGHT_KTD2801
also needs to ensure GPIOLIB is enabled. Otherwise:

WARNING: unmet direct dependencies detected for LEDS_EXPRESSWIRE
  Depends on [n]: NEW_LEDS [=n] && GPIOLIB [=n]
  Selected by [y]:
  - BACKLIGHT_KTD2801 [=y] && HAS_IOMEM [=y] && BACKLIGHT_CLASS_DEVICE [=y]

This unmet dependency was found by kconfirm, a static analysis tool for
Kconfig.
