arm: imx: add i.MX53 Beckhoff CX9020 Embedded PC

From: Patrick Bruenn <[email protected]>

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 <[email protected]>

---

Changes in v3:
- replace CONFIG_TARGET_MX53CX9020 with CONFIG_MX53 in dts/Makefile
- remove redundant CONFIG_DISPLAY_BOARDINFO from mx53cx9020.h

Changes in v2:
- remove #include <asm/errno.h> from mx53cx9020.c
- remove obsolete CONFIG_CMD_CCAT from mx53cx9020.h
