Usage of lists_bind_fdt() in bind command imposes to add
a compatible string for bind-test node.
Others impacts are:
- bind-test node is binded at sandbox start, so no need to bind it
in test_bind_unbind_with_node() test.
- As explained just above, after sandbox start, now a phy exist.
In test/dm/phy.c, it was verified that a third phy didn't exist,
now we must verified that a fourth phy doesn't exist.
