ARM: dts: rockchip: EMAC Rockchip for RK3066 SoCs and MarsBoard RK3066

This patches serie adds EMAC Rockchip support for RK3066 SoCs and defines an initial devicetree source for MarsBoard RK3066.

changes since v2:
- Squashed patch 1,2 and 4 together (this is the the second patch)
- Add dual-licensing for rk3066a-marsboard.dts
- Renamed regulator "vaux33_reg" to "vcc_rmii" as it is written in the schematic

changes since v1:
- Replaced hoayuelectronics by hoayu as suggested by the vendor-prefix doc in dt-bindings

1.9.1

This patch adds the right pins topology for the MAC and MDIO found in RK3066 SoCs. Boards based on this SoC have an initial support for the emac-rockchip dt-binding.

1.9.1

This patch adds initial support for the Marsboard RK3066. It enables EMAC Rockchip which is the ethernet support on the board and registers it as a supported rockchip platform.

applied to my dts branch for 3.19, with two small changes:

- remove FSF address in license header, per checkpatch warning
[I guess the sunxi header I copied it from also contained the address]
- rename vcc_sd0: fixed-regulator to vcc_sd0: sdmmc-regulator to prevent future naming conflicts with more fixed regulators
