[PATCH v3 3/4] ARM: dts: rockchip: add grf register compatible for rk3066/rk3188

[Johan Jonker <jbx6244@xxxxxxxxx>]

With the conversion of syscon.yaml minItems for compatibles
was set to 2. Current Rockchip rk3xxx.dtsi file only uses "syscon"
for the grf registers. Add "rockchip,rk3066-grf", "syscon"
compatible for rk3066/rk3188 to reduce notifications produced with:

make ARCH=arm dtbs_check
DT_SCHEMA_FILES=Documentation/devicetree/bindings/mfd/syscon.yaml
