It should be possible to make final defines even simpler by using some
wildcard magic. You could avoid defining SOC then.

Please take a look at the:
target/linux/bcm53xx/image/Makefile

It has some magic² code as follows:
DEVICE_DTS := $(patsubst %.dtb,%,$(notdir $(wildcard $(if $(IB),$(KDIR),$(DTS_DIR))/*-$(subst _,-,$(1)).dtb)))

If you could adopt above magic to the bcm4908 it would be great. If not
your suggested solution is probably still better than what we have now.
