[U-Boot] [PATCH] scripts/Makefile.extrawarn: Silence more DTC warnings

[Tom Rini]

While our "extrawarns" logic has gotten out of sync with upstream
Kbuild, for now lets start by bringing in the latest set of DTC_FLAGS
from the Linux Kernel 5.0 to match their behavior in silencing warnings
from dtc.
