From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

get_phy_device() has now become just a wrapper for phy_device_create()
with the phy_id argument set to PHY_ID_NONE. Let's remove this function
treewide and replace it with opencoded phy_device_create(). This has the
advantage of being more explicit about the PHY not having the ID set
when being created.
