net: lan969x: add RGMII registers
Configuration of RGMII is done by configuring the GPIO and clock settings in the HSIOWRAP target, and configuring the RGMII port devices in the DEVRGMII target. Both targets contain registers replicated for the number of RGMII port devices, which is two. Add said targets and register macros required to configure RGMII.
