Subject: [PATCH v4 1/3] ARM64: dts: rockchip: make rk3399's grf a "simple-mfd"

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.

Signed-off-by: Brian Norris <briannorris@...omium.org>

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