imx-ocotp is implemented based on nvmem which can have data cells
as child node. Update the binding doc to reflect it to be more easily
understood by users.

48c926cd34 dt-bindings: Remove leading zeros from bindings notation
Improve the binding example by removing all the leading zeros to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have leading 0s

Converted using the following command:

perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"`

Some unnecessary changes were manually fixed.
