phy: Set phy->dev to NULL when generic_phy_get_by_index_nodev() fails
Generic phy helpers typically use generic_phy_valid() to determine if
the helper should perform its function on a passed struct phy.
generic_phy_valid() treat any struct phy having phy->dev set as valid.
With generic_phy_get_by_index_nodev() setting phy->dev to a valid struct
udevice early, there can be situations where the struct phy is returned
as valid when initialization in fact failed and returned an error.
Fix this by setting phy->dev back to NULL when any of the calls to
of_xlate ops, device_get_supply_regulator or phy_alloc_counts fail. Also
extend the dm_test_phy_base test with a test where of_xlate ops fail.
Fixes: 72e5016f878d ("drivers: phy: add generic PHY framework")
Fixes: b9688df3cbf4 ("drivers: phy: Set phy->dev to NULL when generic_phy_get_by_index() fails")
