We get a warning about missing unit name for soc node, so add it.

So Amit Pundir noted that this patch is causing 5.4-rc to no longer
boot on db845 w/ AOSP, due to it changing the userland sysfs paths
from "/devices/platform/soc/1a00000.mdss" to
"/devices/platform/soc@0/1a00000.mdss"

Is there a better solution here that might not break userspace?

thanks

Other than doing the right thing of not relying on
/sys/devices/platform/* paths, implement per target/file DTC_FLAGS
similar to CFLAGS. There is another want for this in order to enable
dtc symbols for overlays on a per board basis.
