Subject: [PATCH 1/3] dt-bindings: nvmem: qcom,spmi-sdam: fix example 'reg' property

The SPMI PMIC register region width is fixed and should not be encoded
in the devicetree.

Amend the example with a parent pmic node with the expected
'#address-cells' and '#size-cells' and fix up the 'reg' property.

Fixes: 9664a6b54c57 ("dt-bindings: nvmem: add binding for QTI SPMI SDAM")
Signed-off-by: Johan Hovold <johan+linaro@...nel.org>
