One more abstraction layer is required

[ceremcem]

Currently we are assigning roles (analog input, digital output, PWM, etc...) to pins. However, as we could switch to another MCU while keeping the MCU - board interface intact, we should declare our hardware intention with Pin names and its configuration, and then this configuration should be applied to an MCU.

Benefit of this approach is that when we select a new MCU, those configurations would be applied to new pins without making the detailed pin configuration again. This will save time and prevent human errors.

If we select the MCU first and then configure pins, the upper abstraction (pinNames vs. configuration) should be automatically separated.
