The pinctrl nodes require some extra opaque arguments for the pull up and drive
strength values.
Introduce a new header file and convert the device trees to replace these
opaque numbers by defines.

Replace the various raw GPIO flags by their definition in the common

The current GPL only licensing on the DTSI makes it very impractical for other
software components licensed under another license.
In order to make it easier for them to reuse our device trees, relicense our
device trees under a GPL/X11 dual-license.

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.

Tested on a subset of these boards, for the others boards the settings match
the ones of the tested boards according to the original firmware fex files.

Add nodes for the usb-phy and ehci- and ohci-usb-host controllers.
Based on fex file settings, the fex file also contains a mysterious line:
usb_hub_vcc_en_gpio = port:PB09<1><0><default><0>
Which also clashes with usbc0, which has:
usb_drv_vbus_gpio = port:PB09<1><0><default><0>
So if usb does not work properly we need someone with a hackberry to look
closer into this.

According to Documentation/devicetree/bindings/regulator/regulator.txt
regulator nodes should not be placed under 'simple-bus'.

The chosen nodes are nowadays pretty useless, since they will be overriden by
the bootloader anyway.
We can thus safely remove them.

The Hackberry has a PHY that needs to be powered up through a GPIO, so
we need to use a fixed regulator here.

In the early days, the A10 and A13 shared quite some code. Nowadays it
shares less and less code, the A31 diverging even more, so it doesn't
make much sense to continue to maintain this structure, just use one
DTSI for every SoC, and that's it.

We previously relied on the bootloader to do the muxing of the UART for
the Hackberry. Don't rely on it anymore and use pinctrl.
