arm64: dts: colibri-imx8x: delete adc1 and dsp

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@59580000 rsrc 512 not owned

arm64: dts: colibri-imx8x: move pinctrl property from SoM to eval board

Each carrier board device tree except the eval board one already override
iomuxc pinctrl property to configure unused pins as gpio.
So move also the pinctrl property to eval board device tree.
Leave the pin group definition in imx8x-colibri.dtsi to avoid duplication
and simplify configuration of gpio.

arm64: dts: colibri-imx8x: fix eval board pin configuration

Fix pinctrl groups to have SODIMM 75 only in one group.
Remove configuration of the pin at SoM level because it is normally
used as CSI_MCLK at camera interface connector.
Without this fix it is not possible, without redefining iomuxc pinctrl,
to use CSI_MCLK signal and leads to the following error messages:

imx8qxp-pinctrl scu:pinctrl: pin IMX8QXP_CSI_MCLK already requested
