For devm_phy_destroy(), its comment says it needs to invoke phy_destroy()
to destroy the phy, but it will not actually invoke the function since
devres_destroy() does not call devm_phy_consume(), and the missing
phy_destroy() call will cause that the phy fails to be destroyed.

Fortunately, the faulty API has not been used by current kernel tree.
Fix by using devres_release() instead of devres_destroy() within the API.
