Add MCU_DEVICE to presets-example.mk

[ClemensGruber]

In case you update the PyCom firmware via the sandbox tool and make install-pycom-firmware you have to specify MCU_DEVICE

[ADVICE] Please adjust the "MCU_DEVICE" environment variable like export MCU_DEVICE=FiPy

Is there a reason why MCU_DEVICE is currently not in the presets-example.mk? E.g. conflicts in case there is a non-PyCom device connected or other circumstances?

If this is not the case please consider to merge this pull request. ;-)

Seems that adding MCU_DEVICE is not sufficient had still to call export MCU_DEVICE=FiPy

And even with this it is not working on WSL

--port " COM10"

The number is correct, in presets.mk

MCU_PORT ?= /dev/ttyS10

and this is working e.g. with make repl

root@XPS13-CGruber:/home/cgruber/hiveeyes/sources/hiveeyes-micropython-firmware# make repl
Device port: usb => /dev/ttyS10
.venv3/bin/rshell --port /dev/ttyS10 --user micro --password python --buffer-size 2048 repl
Using buffer-size of 2048

even if I change MCU_PORT in presets.mk this is respected, but it seems to work not correctly with make install-pycom-firmware in combination with WSL.

I think we should forget it, we can use the Windows shell for this task or the GUI tool PyCom Firmware Updater. Just tried it out to have all things "at one place", but no problem to make it on different places.
