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.

The current GPL only licensing on the DTSI makes it very impractical for other
software components licensed under another license.

This patch adds the regulator nodes for the axp209 by including
the axp209 dtsi. As the inputs of these regulators are from the
axp209's PS output, which is basically just a mux over the 2
inputs, it is considered to be unregulated. Thus we do not provide
input supply properties for them.

The regulator names and constraints are based on the board
schematics and the SoC datasheet.

DCDC2 is used as the cpu power supply. This patch also references
it from the cpu node.

Also get rid of axp209 properties already set in axp209.dtsi.

At a node for the axp209, and where necessary the i2c controller to the dts
for various boards. Note the axp209 regulators are omitted as we don't have
any use for them yet, and on some boards were not sure how exactly they are
wired up.

Adding support for just the axp209 without the regulators is still useful, as
it will give us power-button and poweroff support.

There is several different SoCs sharing the sun5i codename: A10s, A12
and A13. Since there is enough differences to not consider those the
same SoCs, change a bit the naming scheme to reflect this.

Moreover, some boards like the olinuxino come in A10s and A13 variants,
which also share the same SoC codename.

So change the naming scheme to reflect both the codename and the market
name of the SoCs used in the dtsi and in the board files
