Enable IMX577 via CCI on Taloss EVK Core Kit.
The Talos EVK board does not include a camera sensor
by default, this DTSO has enabled the Arducam 12.3MP

Please remind me, what does dtbo-y Makefile target serve for?

I checked, dtbo- is not an upstream usage, it will be updated form dtbo-$(CONFIG_ARCH_QCOM) to dtb-$(CONFIG_ARCH_QCOM) in the next version.
Thanks,
