arm, imx6, dts: add DT for aristainetos2 board

This patch add support for the imx6dl based aristainetos2 board with following configuration:

CPU:   Freescale i.MX6DL rev1.1 at 792 MHz
MReset cause: POR
MBoard: aristaitenos2
DRAM:  1 GiB
NAND:  1024 MiB
MMC:   FSL_SDHC: 0, FSL_SDHC: 1
SF: Detected N25Q128A with page size 256 Bytes, erase size 64 KiB, total 16 MiB
Display: lb07wv8 (800x480)

As this board can used with 2 different display types, the differences between them are extracted into 2 DTS files, and the common settings are collected in a common file.

Changes in v4:
- add comments from Philipp Zabel:
- fix some typos
- fix license text
- fix pmic compatible name to "dlg,da9063"
- remove clocks property from i2c4 node
- use simple panel driver, so remove the fsl,data-mapping and fsl,data-width properties and the display-timings node. need patch: "drm/panel: Add support for LG LB070WV8 800x480 7" panel"

Changes in v3:
- add comments from Shawn Guo
- change license to GPL/X11 dual licence
- rename touch node name to "touch"
- add DTB in Makefile
- remove "status = "okay"" from backlight node
- rename "pinctrl_ipu1_1_80Ohm_clk" to "pinctrl_ipu_disp"
- remove "status = "okay"" from "display@di0" node
- remove "dma-names;" in ecspix nodes
- use macro for clock ID and gpio
- move iomuxc to the bottom of the file
- configure pinctrl_backlight in the device node, not from the hog group
- provide a proper pad configuration value rather than 0x8000000.
- in the iomuxc node, save one level of the sub-node
needs patch:
LinusW queued patch 5fcdf6a7ed95 ("pinctrl: imx: Allow parsing DT without function nodes")
- add comments from Philipp Zabel
- get rid of "fsl,panel" to connect a drm_panel to the parallel-display instead switch to the common of-graph bindings.
need patch: "drm/imx: parallel-display: fix drm_panel support" from Philipp Zabel

Changes in v2:
- add comments from Sascha Hauer:
- remove "clock-frequency" property in i2c nodes
- correct indentation in some pinctrl nodes
- move pin settings out of "gpiogrp" where it was possible led pins not moved, as they used through sysfs

Changes in v4:
- new in version 4, as Philipp Zabel suggested to use simple panel driver

Changes in v3: None
Changes in v2: None

Applied, thanks. For future patches, please make sure to send them to my GMail account (as listed in MAINTAINERS). Corporate email is known to corrupt patches occasionally, though it seems to have worked fine this time.
