The I2C's, MMC0 and EMAC controllers have only one muxing option in the
SoC. In such a case, we can just move the muxing into the DTSI, and remove
it from the DTS.

All our pinctrl nodes were using a node name convention with a unit-address
to differentiate the different muxing options. However, since those nodes
didn't have a reg property, they were generating warnings in DTC.
In order to accomodate for this, convert the old nodes to the syntax we've
been using for the new SoCs, including removing the letter suffix of the
node labels to the bank of those pins to make things more readable.

The gpio pinctrl nodes are redundant and as such useless most of the times.
Since they will also generate warnings in DTC, we can simply remove most of
them.

All dts files for the sunxi platform have been switched to the generic
pinconf bindings. As a result, the sunxi specific pinctrl macros are
no longer used.
Remove the #include entry with the following command:
sed --follow-symlinks -i -e '/pinctrl\/sun4i-a10.h/D' \
arch/arm/boot/dts/sun?i*.*
arch/arm/boot/dts/sun9i-a80.dtsi was then edited to remove the extra

The blue led on the Mele A1000 is wired to light up as soon as the board
has powered (it will be on while the gpio is still in input / floating
mode), also its location on the top-set box clearly signals "power led".
Until now we've been treating this as a generic usr function led, which
means that when you plug power into the top-set box, the power-led lights
and then turns off as soon as the kernel loads, which looks wrong.
This renames the led from a1000:blue:usr to a1000:blue:pwr and marks
it as default on, fixing this.

It seems that recent kernels have a shorter timeout when scanning for
ethernet phys causing us to hit a timeout on boards where the phy's
regulator gets enabled just before scanning, which leads to non working
ethernet.
A 10ms startup delay seems to be enough to fix it, this commit adds a
20ms startup delay just to be safe.
This has been tested on a sun4i-a10-a1000 and sun5i-a10s-wobo-i5 board,
both of which have non-working ethernet on recent kernels without this
fix.

Add UART aliases and stdout-path property for all the Allwinner boards so that
we won't have to rely on the bootargs' console= value, while working with
legacy bootloaders.
While we're at it, also remove the mentions of earlyprintk in the bootargs,
that will remove our default bootargs entirely, and allow the kernel to boot on
a system even if DEBUG_LL is configured for another system.
