This is actually a problem I had to deal with way in the begging of
ARM64.  What was done in the github tree was to have the one of the
DTS
   files(in this case 64) #include the 32 bit dts.  That way it's
not
needed to have the symbolic link and install should work.

I know it's ulgy, but it works...

Take a look at:
https://github.com/raspberrypi/linux/blob/rpi-4.10.y/arch/arm64/boo
t/dt
s/broadcom/bcm2710-rpi-3-b.dts

Here is what the file contains:
#define RPI364

#include "../../../../arm/boot/dts/bcm2710-rpi-3-b.dts"

This do not work in the context of the split device-tree repository
[0] 
(where the directory structure differs).

[0] 
https://git.kernel.org/cgit/linux/kernel/git/devicetree/devicetree-re
basing.git/

Well, two other options would be to simply duplicate the device tree
files. I know that's a pain...

The other option is choose one or the other(arm64 vs. arm32), I would
guess pick arm32.  It works...  And at this time, arm64 doesn't have a
whole bunch of benefit on the RPI 3.  Perhaps maybe a RPI 4 will come
out someday and we will see more of a gain.
