Per the examples in
Documentation/devicetree/bindings/phy/rockchip-emmc-phy.txt, we need the
grf node to be a simple-mfd in order to properly enumerate child devices
like our eMMC PHY.

v4:

 * New, split out of patch 2, per Heiko's recommendation

applied all 3 for 4.8 with the received Reviews.

Please keep the arm64 lower-case and carry over already received 
Acks/Reviews (Shawn and Doug on patch2 in v2).
