[PATCH 08/15] net: phy: check the PHY presence in get_phy_id()

From: Bartosz Golaszewski <bgolaszewski at baylibre.com>
get_phy_id() is only called from get_phy_device() so the check for the
0x1fffffff value can be pulled into the former. This way it'll be easier
to remove get_phy_device() later on.
