ARM: dts: msm: Fix kernel warning for sm8150

When we compile kernel, we will get some similar warnings as follows:
Warning (reg_format): "reg" property in /fragment@4/__overlay__/
qcom,pm8150l@5/qcom,amoled/oledb@e000 has invalid length (8 bytes)
(#address-cells == 2, #size-cells == 1)
Warning (reg_format): "reg" property in /fragment@35/__overlay__/
qcom,camera-flash@0 has invalid length (8 bytes) (#address-cells
== 2, #size-cells == 1)

To fix these compile warnings, "#address-cells" and "#size-cells"
attributes are added in the necessary location.
