ipq806x: add support for OpenMesh A42

* QCA IPQ401x
* 256 MB of RAM
* 32 MB of SPI NOR flash (s25fl256s1)
  - 2x 15 MB available; but one of the 15 MB regions is the recovery image
* 2T2R 2.4 GHz
  - QCA4019 hw1.0 (SoC)
  - requires special BDF in QCA4019/hw1.0/board-2.bin with
    bus=ahb,bmi-chip-id=0,bmi-board-id=16,variant=OM-A42
* 2T2R 5 GHz
  - QCA4019 hw1.0 (SoC)
  - requires special BDF in QCA4019/hw1.0/board-2.bin with
    bus=ahb,bmi-chip-id=0,bmi-board-id=17,variant=OM-A42
* multi-color LED (controlled via red/green/blue GPIOs)
* 1x button (reset; kmod-input-gpio-keys compatible)
* external watchdog
  - triggered GPIO
* 1x USB (xHCI)
* TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX)
* 2x gigabit ethernet
* powered only via POE
  - 802.3af POE on Ethernet 1
  - 18-24v passive POE (mode B) on Ethernet 2

The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the factory image to the u-boot when the device boots up.

# The U-Boot loader of the OpenMesh devices requires image sizes and
# checksums to be provided in the U-Boot environment.
# The OpenMesh devices come with 2 main partitions - while one is active
# sysupgrade will flash the other. The boot order is changed to boot the
# newly flashed partition. If the new partition can't be booted due to
# upgrade failures the previously used partition is loaded.

# detect to which flash region the new image is written to.
#
# 1. check what is the mtd index for the first flash region on this
# device
# 2. check if the target partition ("inactive") has the mtd index of
# the first flash region
#
# - when it is: the new bootseq will be 1,2 and the first region is
# modified
# - when it isnt: bootseq will be 2,1 and the second region is
# modified
#
# The detection has to be done via the hardcoded mtd partition because
# the current boot might be done with the fallback region. Let us
# assume that the current bootseq is 1,2. The bootloader detected that
# the image in flash region 1 is corrupt and thus switches to flash
# region 2. The bootseq in the u-boot-env is now still the same and
# the sysupgrade code can now only rely on the actual mtd indexes and
# not the bootseq variable to detect the currently booted flash
# region/image.
#
# In the above example, an implementation which uses bootseq ("1,2") to
# detect the currently booted image would assume that region 1 is booted
# and then overwrite the variables for the wrong flash region (aka the
# one which isn't modified). This could result in a device which doesn't
# boot anymore to Linux until it was reflashed with ap51-flash.
