Peter Griffin 4edf654be5 phy: add new phy_notify_state() api
Add a new phy_notify_state() api that notifies and configures a phy for a
given state transition.

This is intended to be used by phy drivers which need to do some runtime
configuration of parameters that can't be handled by phy_calibrate() or
phy_power_{on|off}().

The first usage of this API is in the Samsung UFS phy that needs to issue
some register writes when entering and exiting the hibernate link state.
