Subject: [PATCH v3] ARM: dts: Add support for Liebherr's BK4 device (vf610 based)

This commit adds DTS support for BK4 device from Liebherr. It
uses vf610 SoC from NXP.

Signed-off-by: Lukasz Majewski <lukma@...x.de>
---
Changes for v3:

- Rename regulator-vcc_3v3_mcu -> regulator-vcc3v3mcu
- Add a blank line between properties and node @ mdio
- Rename rtc and eeprom node's labels and names
- Rename flash nodes
- Rename 'gpio_leds' -> 'gpioledsgrp'
- Move 'pinctrl_qspi0: qspi0grp' to be in alphabetic order

Changes for v2:

- Rename enet_ext and audio_ext oscillator names
- Move regulators from simple-bus (and rename to reg_3p3v: regulator-3p3v)
- Add stdout-path property to chosen node
- Move iomuxc node to the end (as it is so large)
- Sort with alphabetical order
- Rename the default pinctrl to "hog"
- Move LED pins definition from "hog" to "led" group
- Add more descriptive names to default pins pinmux definition
- Use spi-slave property to describe node working in this mode
- Rename the spidev3 node to slave
- Introduce new compatible name (lwn,bk4) for spidev driver (to avoid
  confusion)
- Update some compatibles to match current kernel
