Commit Message

SPMI devices typically have a single address cell and no size cell,
i.e. reg = <0xf000> for the audio codec instead of reg = <0xf000 0x200>.

The example is a bit misleading because it uses the latter. Copying
this into the device tree would be incorrect and was fixed before for
pm8916.dtsi in commit c2f0cbb57dba ("arm64: dts: qcom: pm8916: Remove
invalid reg size from wcd_codec").

Make the example more clear by adding the outer "pmic" node which
specifies the same #address/size-cells that would be used in the
real deivce tree.
