Revert "of: search the best compatible match first in __of_match_node()"

This reverts commit a28ce1b1750cf9b9e25a7238a28b2934433c99a0.
As pointed out by Grant Likely, we should also take the type and name
into account when searching the best compatible match. That means the
match with compatible, type and name should be better than the match
just with the same compatible string. So revert this and we will
implement another method to find the best match entry.
