[PATCH 1/2] ARM: tegra: enable ARCH_REQUIRE_GPIOLIB for Tegra114

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

CONFIG_ARCH_TEGRA_114_SOC doesn't currently enable gpiolib, which causes
numerous build problems building a Tegra kernel with only Tegra114
enabled, and not Tegra20 or Tegra30. Enable ARCH_REQUIRE_GPIOLIB to
solve this. However, all Tegra will use gpiolib, so select this option
from ARCH_TEGRA rather than each individual ARCH_TEGRA_*_SOC, to
prevent this problem for any future chips.

Olof, Arnd, These two patches can be applied on top of Tegra's previous
tegra-for-3.9-soc-t114 branch.

I think this (coupled with Hiroshi's "ARM: tegra: Fix build error w/
ARCH_TEGRA_114_SOC w/o ARCH_TEGRA_3x_SOC" is it for build failure fixes,
although I'm queueing up a number of clock driver patches for which I'll
send a pull request in the next few days.
