Since Espressobin Ultra board has a microUSB port with the onboard USB to UART connected to it to be used as a debug UART it makes no sense to require the bootloader to pass console args to the kernel in order to get console working. So, use the "stdout-path" property to enable the UART output on the microUSB port by default.
