[PATCH net-next 2/3] net: stmmac: rk: use device rather than platform device in rk_priv_data

[Russell King (Oracle)]

All the code in dwmac-rk uses &bsp_priv->pdev->dev, nothing uses
bsp_priv->pdev directly. Store the struct device rather than the
struct platform_device in struct rk_priv_data, and simplifying the
code.

[PATCH net-next 3/3] net: stmmac: rk: remove unnecessary clk_mac

[Russell King (Oracle)]

The stmmac platform code already gets the "stmmaceth" clock, so there
is no need for drivers to get it. Use the stored pointer in struct
plat_stmmacenet_data instead of getting and storing our own pointer.
