At i2c address 0x2a is MCU command interface which provides access to GPIOs
connected to Turris Omnia MCU. So define mcu node in Turris Omnia DTS file.

Same change was already sent to U-Boot project together with driver. As
Turris Omnia DTS file is shared between Linux kernel U-Boot, I'm sending
this change also in Linux. There is a plan to write also Linux driver for
Turris Omnia MCU, like there is already in U-Boot.

Please document the binding, preferably in yaml.
I'm not going to send any new yaml dt binding document as I see that
dt bindings is clearly deprecated project. Either patches for dt
bindings are waiting without any answer for months (maybe year?) or
patches are ignored/not accepted by beyond reasons or there are request
for changes which cannot work on the real hardware or that new yaml
cannot be parsed/validated due to ton of bugs in other schemas.
Sorry, this is just a waste of time and energy to write new those yamls
as it does not bring any value.
