Title: Support whitelist for xml document types

As discussed here (https://github.com/schmittjoh/JMSSerializerBundle/commit/5a9b7e6b62143950726f642da23d7eebf850e389), here is a proposal for a whitelist support concerning xml deserialization with document types.

I updated the doc to give an example:
```
jms_serializer:
visitors:
xml:
document_whitelist:
- ''
```
