To protect the same, Add no-read-write property to prevent read

Can you explain the real need of this?
Is there any issue you are noticing while reading nvmem content from
userspace?
I don't think this is the right way to do this, its misleading in many
ways. Also this should not be a part of DT binding.
If we decide that we need this feature, then better way to do this using
a new Kernel config.
