Merge ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB changes into next/soc

* commit '5c34a4e89c743339f78cafb2f2a826a010f0746a':
  ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
  ARM: uniphier: drop code for old DT binding

These cause a harmless conflict with the clps711x multiplatform
support, and it's easy to resolve.
