Overlay binaries (.dtbo) are currently only built implicitly as dependencies of composite firmware images and are therefore absent from the kernel install output. Even when final DTBs are produced at build time, some distributions rely on standalone DTBOs for runtime selection and application by bootloaders or firmware. Without explicit install targets, DTBOs are not picked up by the standard dtbs_install flow and therefore cannot be packaged alongside DTBs. Add explicit dtb-$(CONFIG_ARCH_QCOM) entries for DT overlays defined in this Makefile so they are installed via dtbs_install, matching existing DTB install behaviour, while excluding EL2 DTBOs as they are not intended for independent use and are only meaningful in conjunction with their base DTBs.

Install Qualcomm camx DTBO except el2 overlay files by adding them to the dtb-$(CONFIG_ARCH_QCOM) build/install list This makes DTBOs available through the standard dtbs_install flow and ensures they are included in distro kernel packages Signed-off-by: Vishwas Udupa <vudupa@qti.qualcomm.com>
