Use the new devm_of_phy_optional_get() helper instead of open-coding the
same operation.
As devm_of_phy_optional_get() returns NULL if either the PHY cannot be
found, or if support for the PHY framework is not enabled, it is no
longer needed to check for -ENODEV or -ENOSYS.
This lets us drop several checks for IS_ERR(), as phy_power_{on,off}()
handle NULL parameters fine.
