[RFC PATCH v3 2/2] ARM: dts: rockchip: fix yaml warnings for rk3288-pmu-sram compatible nodes

[Johan Jonker]

A test with the command below gives for example these warnings:

arch/arm/boot/dts/rk3288-evb-act8846.dt.yaml: sram@ff720000:
'#address-cells' is a required property
arch/arm/boot/dts/rk3288-evb-act8846.dt.yaml: sram@ff720000:
'#size-cells' is a required property
arch/arm/boot/dts/rk3288-evb-act8846.dt.yaml: sram@ff720000:
'ranges' is a required property

Fix this error by adding '#address-cells', '#size-cells' and
'ranges' to the 'rockchip,rk3288-pmu-sram' compatible node
in rk3288.dtsi.

make ARCH=arm dtbs_check
