Subject: meta-agl-bsp: Update Raspberry Pi create-combined-dtb recipe

Update the create-combined-dtb recipe that creates merged dtb files
for netbooting on the Pi 4 to handle the upstream kernel change to a
separate Pi 4 specific version of the vc4-kms-v3d overlay (it now
needs vc4-kms-v3d-pi4.dtbo).  Also remove the Pi 3 support, as AGL
no longer supports it.

Bug-AGL: SPEC-3819
