Convert the device tree bindings for tm2-touchkey to the YAML format.
While we're at it, clarify the descriptions a bit to make it clear that
this driver can be used for many different MCUs that all implement
a similar I2C protocol. Depending on the MCU the voltage requirements
may be different, on some devices the controller uses 2.2V, 2.8V or
even 3.3V for vcc-supply instead of 1.8V.

The Samsung touchkey controllers are often used with external pull-up
for the interrupt line and the I2C lines, so we might need to enable
a regulator to bring the lines into usable state. Otherwise, this might
cause spurious interrupts and reading from I2C will fail.
Document support for a "vddio-supply" that is enabled by the tm2-touchkey
driver so that the regulator gets enabled when needed.

I think the funny pipe | us only needed when you want something to be
fixed-width like ASCII art or ASCII tables. But no big deal I suppose.

Actually, the pipe | effectively means that new lines \n will be
preserved in the parsed output, i.e.
something:
Hello
World
means "Hello World", while
something: |
Hello
World
means "Hello\nWorld\n".
In practice I guess it doesn't make much of a difference for these
descriptions. It also doesn't seem to be used very consistently in
existing device tree bindings, so I think it's fine as-is.
Thanks,
Stephan

Oh that's nice, I learned something new today :D
Combined with fixed-width font it will indeed preserve ASCII gfx too.
But I don't know of a way to guarantee fixed-width :/
https://yaml-multiline.info/ explained even more. Nice!
