[U-Boot] 4 failures with 'ut dm'

Hi Simon,

With current u-boot/master, there are 4 failures with 'ut dm'. I was wondering is this not covered by travis-ci?

Test: dm_test_bus_children: bus.c test/dm/bus.c:112, dm_test_bus_children(): num_devices == list_count_items(&uc->dev_head): Expected 7, got 6

Test: dm_test_fdt: test-fdt.c test/dm/test-fdt.c:184, dm_test_fdt(): num_devices == list_count_items(&uc->dev_head): Expected 7, got 6

Test: dm_test_spmi_access: spmi.c test/dm/spmi.c:55, dm_test_spmi_access(): 0 == device_get_child(bus, 0, &pmic): Expected 0, got -22

Test: dm_test_spmi_access_peripheral: spmi.c test/dm/spmi.c:82, dm_test_spmi_access_peripheral(): 0 == gpio_lookup_name("spmi1", &dev, &offset, &gpio): Expected 0, got -22
