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 ...
