This will list all the String in your map, is that what you want?

<select class="form-control select-checkbox" id="WhatToUpdate" multiple="multiple">
  <th:block th:each="idsAndText : ${deviceidsAndwhatToUpdateText}">
    <option th:each="text : ${idsAndText.value}" th:value="${text}" th:text="${text}" />
  </th:block>
</select>
