phy: cadence-torrent: remove noop_ops phy operations

Even if a PHY is already configured, the PHY operations are needed during
resume stage, as the PHY is in reset state.
The noop_ops PHY operations is removed to always have PHY operations.
The already_configured flag is checked at the begening of init, configure
and poweron operations to keep the already_configured behaviour.
