In commit 6f46c7441a9f ("phy: cadence: Sierra: Add a UCLASS_PHY device for
links"), a separate udevice of type UCLASS_PHY was created for each link.
Therefore, move the corresponding link operations under the link device.

Also, change the uclass of sierra phy to UCLASS_MISC as it is no longer the
phy device.
