[PATCH] phy: Return NULL if the PHY is optional (part two)

[Geert Uytterhoeven]

If we're trying to get a handle to an optional PHY, then the PHY
framework being disabled shouldn't return a hard error.

Instead, return NULL just like phy_optional_get() does when there's no
PHY provided in the DT.

Based on commit 11a6e41c0ee503ff ("phy: Return NULL if the phy is
optional"), which did the same thing for devm_phy_optional_get().

It seems there were never any in-tree users of this function since its
introduction in 788a4d56ff378bff ("drivers: phy: Add support for
optional phys") in v3.14.
Perhaps it should be removed?
