Add CX9020 board based on mx53loco. Add simplified imx53 base device tree from kernel v4.8-rc8, to reuse serial_mxc with DTE and prepare for device tree migration of other functions and imx53 devices. The CX9020 differs from i.MX53 Quick Start Board by: - use uart2 instead of uart1 - DVI-D connector instead of VGA - no audio - CCAT FPGA connected to emi - enable rtc Signed-off-by: Patrick Bruenn <p.bruenn@beckhoff.com>
