Style fixes

Fix minor style fixes and typos:
1. Change file name to correct one.
2. Change copyright year.
3. Insert whitespaces before and after paranthesis.
4. Put `*` next to pointer name.

- * \brief               This function calculates the full generic CMAC
- *                      on the input buffer with the provided key.
- *
- *                      The function allocates the context, performs the
- *                      calculation, and frees the context.
- *
- *                      The CMAC result is calculated as
- *                      output = generic CMAC(cmac key, input buffer).
- *
- *
- * \param cipher_info   The cipher information.
- * \param key           The CMAC key.
- * \param keylen        The length of the CMAC key in bits.
- * \param input         The buffer holding the input data.
- * \param ilen          The length of the input data.
- * \param output        The buffer for the generic CMAC result.
- *
- * \return              \c 0 on success.
- * \return              #MBEDTLS_ERR_MD_BAD_INPUT_DATA
- *                      if parameter verification fails.
