net: arc_emac: make the rockchip emac document more compatible

Add the rk3036 SoCs to match driver for document since the emac driver
has supported the rk3036 SoCs.

This patch adds the rk3036/rk3066/rk3188 SoCS to compatible for rockchip
emac ducument. Also, that will suit for other SoCs in the future.
