Base dt bindings for mikrobus addon boards. Contains properties that are part of all types of boards (SPI, I2C, etc). Each pin in mikroBUS connector can either be used for it's original purpose (UART, I2C, SPI, etc) or as a normal GPIO. Introducing `pinctrl-apply` allows selecting the pin configuration by name. Note: Some mikrobus-connectors might not support all valid pinctrl.
