Refresh armadillo800eva_defconfig, and enable missing options for devices
in platform data and/or DT:
  - REGULATOR_GPIO
  - LEDS_GPIO

Do we want SHMOBILE_IOMMU, too? The help text says "If unsure, say N."
If yes, is the default SHMOBILE_IOMMU_ADDRSIZE_2048MB OK?

I would prefer if changes were made in a more incremental patch.

* A patch to enable LEDS_GPIO and REGULATOR_GPIO.
* Then a cleanup patch, if you really want to do that: but why?

OK, will do for v2, when I know more about SHMOBILE_IOMMU.

It's a good idea to run a "make savedefconfig" once in a while, to get rid of
stale symbols, and symbols that are now auto-selected.
Anyway, although there were quite some changes in the actual defconfig, the
net impact on "make armadillo800eva_defconfig" is much smaller than I expected
(only CONFIG_NET_VENDOR_SAMSUNG gets enabled), so I'll leave the regular
refreshing to you ;-

I agree that its nice to keep things up to date. But there
is a goal to eventually remove the per-board defconfigs.
So my motivation to spruce things up is a little lower than
it might otherwise be.

I think it's best to go with a "N" here. Unless someone can prove to
me that we need it and that it is working!

In general I'd like to begin by integrating IOMMU support for R-Car
Gen2 in a controlled manner and once that is in place I think we can
revisit this older case. At that time hopefully we will be dealing
with the multiplatform defconfig for r8a7740 and Armadillo.

Cheers,

/ magnus
