Allwinner conversion to generic pin muxing properties

Here is a list of patches that converts the current DT to the generic pin
control and muxing properties, now that the pinctrl driver supports it.

I dropped the ball on this over the holidays for a few reasons, none of them
good. Unfortunately we're at -rc3+ now, so I've queued this up in next/dt for
v4.11 at this point. Hope that's alright.

You might want to use your branch as a base for new DT contents for
v4.11 in case it ends up being conflict-heavy, which would work fine at our
end.

It is, there's no rush.

There might be one minor (and trivial) conflict with one of the fix
I'll send your way, but that pretty much it. All the other patches
were based on this one already.

Thanks!

We might have conflicts with this unfortunately.

It turns out that we fixed an issue where the pinctrl driver in 4.10
is now honoring the case where we list our pull-ups as disabled, while
it used to be ignored (which was the bug).

However, some boards were listing improperly in their DT that their
pull-ups were disabled, while they actually needed it, which means
that now the driver will disable them, and things get broken (mostly
MMC for now, but I expect other devices to be broken too).

We have two ways of fixing this.

Option 1 is applying a patch that will enable the pull ups on the MMC
devices (because it's ok to do so) that was queued with 4.11 and will
conflict heavily with this PR.

The other option would be to queue the two first patches of that PR as
fixes that will reintroduce the previous behaviour (or at least, the
one the boards expects). I'm guessing in that case, the merge will
just work (since it's the exact same commits anyway), and we fix all
the devices and not just MMC. This has not been confirmed to work at
the moment though, but should be very soon.

What do you think?
Maxime

Isn't the third and easiest option to revert back the old behavior on
the pinctrl driver for 4.10? Sounds like that could (possibly) be just
a one-line change somewhere?

Then, for 4.11, bring it back once the DT contents is fixed up.
