As of commit 32b9c61307629ac7 ("Preserve datatype markers when emitting
dts format") in dtc v1.4.7, "dtc -O dts" no longer outputs compatible
properties containing multiple values as multiple strings. Instead, it
outputs single strings, where the individual values are internally
separated by an escaped nul character.
Fix this by translating nul-separated compatible values to the
traditional multi-string format before splitting them.
