RPi 5 config uses BR2_LINUX_KERNEL_INSTALL_INTREE_OVERLAYS which builds the device tree overlays from the Linux tree when building the kernel. The overlays directory also contains overlay_map.dtb which is necessary to correctly map overlays without RPi version suffix to the platform-specific ones. Without this, some peripherals may not work correctly on Pi 5 without any obvious error messages in the kernel log because an incorrect (Pi 4) overlay is used as the default.
Fixes #3321
