ARM: dts: rockchip: add QoS register compatibles for rk3288

With the conversion of syscon.yaml minItems for compatibles
was set to 2. Current Rockchip dtsi files only use "syscon" for
QoS registers. Add Rockchip QoS compatibles for rk3288
to reduce notifications produced with:

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