net: stmmac: dwmac-rk: add rk3366 & rk3399 specific data

Browse Source 
Add constants and callback functions for the dwmac on rk3228/rk3229 socs.
As can be seen, the base structure is the same, only registers and the
bits in them moved slightly.

The device node has following properties.
Required properties:
- compatible: Can be one of "rockchip,rk3228-gmac", "rockchip,rk3288-gmac",
"rockchip,rk3368-gmac"
- compatible: should be "rockchip,<name>-gamc"
"rockchip,rk3228-gmac": found on RK322x SoCs
"rockchip,rk3288-gmac": found on RK3288 SoCs
"rockchip,rk3366-gmac": found on RK3366 SoCs
"rockchip,rk3368-gmac": found on RK3368 SoCs
"rockchip,rk3399-gmac": found on RK3399 SoCs
- reg: addresses and length of the register sets for the device.
- interrupts: Should contain the GMAC interrupts.
- interrupt-names: Should contain the interrupt names "macirq".
