package/rpi-firmware: select BR2_LINUX_KERNEL_DTB_OVERLAY_SUPPORT when needed

Browse Source 
When BR2_PACKAGE_RPI_FIRMWARE_INSTALL_DTB_OVERLAYS is enabled, and the
DTBs are built by Linux (i.e BR2_LINUX_KERNEL_DTS_SUPPORT is enabled),
these DTBs should be built with the -@ Device Tree compiler option, so
that they can be used together with DTB overlays. So let's select
BR2_LINUX_KERNEL_DTB_OVERLAY_SUPPORT in this situation.
