Add initial dtsi file to support Marvell Berlin4CT SoC with
quad Cortex-A53 CPUs.

It also adds dts file for Marvell Berlin4CT DMP board which is
based on Berlin4CT SoC.

Just earlycon without any parameters will suffice. Currently earlycon
parsing code has issues and it's being worked out[1]. The serial port
details specified in stdout-path will be used by earlycon.

I just found all arm64 ports don't have bootargs, so neither earlycon, I will
follow this behavior. Will send out v4 later.

Thanks
