Subject: [RFC PATCH 2/2] dt-bindings: sram: fix yaml warnings for rk3288-pmu-sram compatible nodes

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

arch/arm/boot/dts/rk3288-evb-act8846.dt.yaml: sram@...20000:
'#address-cells' is a required property
arch/arm/boot/dts/rk3288-evb-act8846.dt.yaml: sram@...20000:
'#size-cells' is a required property
arch/arm/boot/dts/rk3288-evb-act8846.dt.yaml: sram@...20000:
'ranges' is a required property

Fix this error by making '#address-cells', '#size-cells' and
'ranges' required for all compatible strings except for
'rockchip,rk3288-pmu-sram'.
