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.
