[PATCH v6 3/6] phy: core: Fix that API devm_phy_destroy() fails to destroy the phy

[Zijun Hu]

From: Zijun Hu <quic_zijuhu at quicinc.com>

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.

Why to fix the API here instead of directly deleting it?

1) it is simpler, just one line change.
2) it may be used in future.
3) ensure this restored API right if need to restore it in future
   after deleting.

Anyone may remove such APIs separately later if he/she cares.
