The ipa_control_range_data structure is only used to document the IPA control serialization format, but isn't used in code at all as the ControlRange entries are directly serialized to a byte stream buffer. This applies to the ipa_control_value_data structure that is solely used by ipa_control_range_data. Expand the documentation of the IPA control serialization format to describe the layout of the control range data in words and diagrams instead of through a C structure. Remove the unused structures as a result.
