[Buildroot] [git commit branch/2020.02.x] configs/raspberrypi{3, 4}_64: enabling BR2_LINUX_KERNEL_DTB_OVERLAY_SUPPORT no longer needed

commit: https://git.buildroot.net/buildroot/commit/?id=9f6504fc5912386ecb07a95b2c90f8a88b4a8b3f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.02.x

BR2_LINUX_KERNEL_DTB_OVERLAY_SUPPORT is now forcefully selected by
BR2_PACKAGE_RPI_FIRMWARE_INSTALL_DTB_OVERLAYS when the kernel is in
charge of building DTBs (BR2_LINUX_KERNEL_DTS_SUPPORT=y). So enabling
BR2_LINUX_KERNEL_DTB_OVERLAY_SUPPORT is no longer needed in the 64-bit
defconfigs for Raspberry Pi 3 and 4.
