Building out of tree dtbs

[Chris Packham]

(resend without HTML part)

Hi,

I just noticed with the latest 6.12-rc I'm no longer able to build an 
out of tree dtb by just copying it into arch/$ARCH/boot/dts (at least 
for ARCH=mips and ARCH=arm64) and running `make my-board.dtb`. I believe 
buildroot relies on this as well[1].

Is this an intentional change? Is it too late to undo it (or provide an 
alternative way of having out of tree dts that make use of in-tree dtsi).

Thanks,
Chris
