Subject: [PATCH net-next v2 1/3] net: stmmac: dwmac-qcom-ethqos: Use of_get_phy_mode() over device_get_phy_mode()

Since this driver only uses devicetree, let's move over to
of_get_phy_mode(). That API has an explicit error return and produces a
phy_interface_t directly instead of an int when representing the phy
mode.

Signed-off-by: Andrew Halaney <ahalaney@...hat.com>

Changes since v1:
    * Convert to using of_get_phy_mode() instead of continuing to use
      device_get_phy_mode() (Andrew Lunn)
