Commit b4d7263bc3b6 ("kernel: of: avoid some unnecessary bad cell count
warnings") backported Linux commit 6e5773d52f4a ("of/address: Fix WARN
when attempting translating non-translatable addresses"), which started
requiring #address-cells for a device's parent if we want to use the
reg resource in a device node.
Many Chromium devices use a /firmware/coreboot device node that is
patched in by the boot firmware. These structures look something like:
# find /sys/firmware/devicetree/base/firmware/
/sys/firmware/devicetree/base/firmware/
/sys/firmware/devicetree/base/firmware/scm
/sys/firmware/devicetree/base/firmware/scm/compatible
/sys/firmware/devicetree/base/firmware/scm/name
/sys/firmware/devicetree/base/firmware/ranges
/sys/firmware/devicetree/base/firmware/chromeos
/sys/firmware/devicetree/base/firmware/chromeos/fmap-offset
/sys/firmware/devicetree/base/firmware/chromeos/compatible

/sys/firmware/devicetree/base/firmware/chromeos/vboot-shared-data
/sys/firmware/devicetree/base/firmware/chromeos/nonvolatile-context-offset
/sys/firmware/devicetree/base/firmware/chromeos/firmware-version
/sys/firmware/devicetree/base/firmware/chromeos/nonvolatile-context-size
/sys/firmware/devicetree/base/firmware/chromeos/name
/sys/firmware/devicetree/base/firmware/coreboot
/sys/firmware/devicetree/base/firmware/coreboot/compatible
/sys/firmware/devicetree/base/firmware/coreboot/board-id
/sys/firmware/devicetree/base/firmware/coreboot/reg
/sys/firmware/devicetree/base/firmware/coreboot/name
/sys/firmware/devicetree/base/firmware/name
Notably, there is no #{address,size}-cells in /firmware.
This breaks any driver relying on a device under /firmware, such as the
coreboot_table driver.
This is technically an ill-formatted FDT, and so we might as well just
add the properties ourselves.

In the transition to nvmem-layout and subsequent disabling of non layout
u-boot-env, this device was left out.

Given that Linksys is the same brand and probably use the same OEM, it
stands to reason all devinfo hw_mac_addr implementations are the same.

Align the ipq806x target to the pattern already used on other devices where
the device DTS are placed in a dedicated directory separate from the files
directory.
This, while trying to enforce a common pattern for every target, also permits to
do modification to device DTS without having to trigger a recompilation of the
entire kernel (as the files directory is not touched)
