[PATCH 12/23] powerpc: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB

[Linus Walleij <linus.walleij@linaro.org>]

This replaces:

- "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can
  now be selected directly.

- "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB
  is now selectable by everyone, so we need not declare our
  intent to select it.

When ordering the symbols the following rationale was used:
if the selects were in alphabetical order, I moved select GPIOLIB
to be in alphabetical order, but if the selects were not
maintained in alphabetical order, I just replaced
"select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

Various arch maintainers:

either ACK this and I will merge it into the GPIO tree for v4.7
anticipating no clashes, or you wait until I have the enabling patch
upstream (patch 1 in this series, removing deps on
ARCH_[WANTS_OPTIONAL|REQUIRES]_GPIOLIB), and you will be able to
merge it to your arch trees yourselves for late v4.7
(post GPIO tree merge) or for v4.8.

You can also ask me for an immutable branch if you prefer that, I
will put the enabling patch on a branch and the patch for your arch
on top and ask you to pull it.

Select your option from the menu, silence probably means I will
merge it to the GPIO tree. Unless you are X86 or ARM in which case
I will be cautious.
