kbuild: Drop phandle from diff between base DT and U-Boot augmented DT if DEVICE_TREE...

Remove the "phandle = <0x..>;" properties from the DT diff between
unpatched base DT and U-Boot augmented DT if DEVICE_TREE_DEBUG=1.
The phandle numbers are only generated by DTC, but not referenced
anywhere in the DT, because the original references are specifically
not replaced by phandle numbers when recent DTC is invoked with the
-I dts -O dts flags . The phandle number are therefore only a noise
in the diff, filter them out.
