Fill ESPRESSObin uart0 node with pinctrl information like in the Armada-3720-DB device tree (which uses the same node). Also explain how to enable the second UART port available on the headers. This second port is not enabled by default because both headers are dedicated to expose general purpose pins and remapping some of them to use the second UART would break existing users.
