[PATCH v1 4/4] arm64: dts: colibri-imx8x: delete adc1 and dsp

[Andrejs Cainikovs]

i.MX8, i.MX8X, i.MX8XP and i.MX8XL SOC device trees are all based on
imx8-ss-*.dtsi files. For i.MX8X and i.MX8XP these device trees
should be updated with some peripherals removed or updated, similar
to i.MX8XL (imx8dxl-ss-*.dtsi files). However, it looks like only
i.MX8 and i.MX8XL are up to date, but for i.MX8X and i.MX8XP some
of the peripherals got inherited from imx8-ss-*.dtsi files, but in
reality they are not present on SOC.
As a result, during resource partition ownership check U-Boot receives
messages from SCU firmware about these resources not owned by boot
partition. In reality, these resources are not owned by anyone, as
they simply does not exist, but are defined in Linux device tree.
This change removes those peripherals, which are listed during
U-Boot resource partition ownership check as warnings:

  ## Flattened Device Tree blob at 9d400000
     Booting using the fdt blob at 0x9d400000
     Loading Device Tree to 00000000fd652000, end 00000000fd67efff ... OK
  Disable clock-controller at 59580000 rsrc 512 not owned
  Disable clock-controller at 5ac90000 rsrc 102 not owned

  Starting kernel ...
