The FSF address triggers a warning on checkpatch, saying that the FSF
license is already present in the Linux source code, and that it has
already changed in the past.

Remove it from our DT, as suggested.

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 Hummingbird A31 has an AMPAK AP6210 WiFi+Bluetooth module. The
WiFi part is a BCM43362 IC connected to MMC1 in the A31 SoC via SDIO.
The IC also takes a power enable signal via GPIO. This is supported
with the new power sequencing bindings.

The WiFi module supports out-of-band interrupt signaling via GPIO,
but this is not enabled yet.

the first one is not working for some reason on the hardware I have been able

This platform from WITS is the evaluation board for the Allwinner A31.
It features a quad-Cortex A7, 2048MB of RAM, NAND, USB, MMC, several
UART, HDMI, a 2048 x 1536 10" screen, powered by a PowerVR, etc.

Of course, most of these peripherals aren't supported yet, but 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

For the new sun4i/Cubieboard (A10) support, lets re-strucure the
sun5i dts files to make it more generic. Those are the new
dts/dtsi files:

sunxi.dtsi - Devices common to all Allwinner sunXi SoC's
sun4i.dtsi - sun4i Devices, will include sunxi.dtsi
sun5i.dtsi - sun5i Devices, will include sunxi.dtsi
board.dts - will include either sun4i.dtsi or sun5i.dtsi
