net: stmmac: rk: convert rk3328 to use bsp_priv->id

rk3328 contains two GMAC instances - gmac2io and gmac2phy. While the
gmac2io instance may be connected to an external PHY, the gmac2phy
instance is permanently connected via RMII to an on-SoC integrated PHY.

The driver currently tests for the gmac2phy instance by checking
bsp_priv->integrated_phy (determined from the PHY's phy-is-integrated
property) and sometimes that the interface mode is RMII. This works
because the rk3328.dtsi has:

	gmac2phy: ethernet@ff550000 {
		compatible = "rockchip,rk3328-gmac";
		phy-mode = "rmii";
		phy-handle = <&phy>;

		mdio {
			phy: ethernet-phy@0 {
				phy-is-integrated;
			};
		};
	};

The driver contains a mechanism to look up the MMIO address in a table
to determine bsp_priv->id, which is used for every other Rockchip
device. Switch rk3328 to use this mechanism to determine bsp_priv->id
and use that to select which GRF register is used for configuration,
similarly to how the other Rockchip SoCs handle such differences.
