Dmitry Baryshkov ef31dc41cf phy: core: don't require set_mode() callback for phy_get_mode() to work ...

[ Upstream commit d58c04e305 ]

As reported by Damon Ding, the phy_get_mode() call doesn't work as
expected unless the PHY driver has a .set_mode() call. This prompts PHY
drivers to have empty stubs for .set_mode() for the sake of being able
to get the mode.

Make .set_mode() callback truly optional and update PHY's mode even if
it there is none.
