dt_find_node() calls dt_read_cell_props() for every node it walks, but
this is only actually necessary when the caller is interested in the
`#address-cells` and `#size-cells` values and passed out-parameters to
receive them. Most callers don't actually do that, and we scan through
all properties needlessly on every node. This patch adds a fast path to
skip that.
