/**
  This command returns various information regarding the TPM and its current state.

  The capability parameter determines the category of data returned. The property parameter 
  selects the first value of the selected category to be returned. If there is no property 
  that corresponds to the value of property, the next higher value is returned, if it exists.
  The moreData parameter will have a value of YES if there are more values of the requested 
  type that were not returned.
  If no next capability exists, the TPM will return a zero-length list and moreData will have 
  a value of NO.

  NOTE: 
  To simplify this function, leave returned CapabilityData for caller to unpack since there are 
  many capability categories and only few categories will be used in firmware. It means the caller
  need swap the byte order for the feilds in CapabilityData.

  @param[in]  Capability         Group selection; determines the format of the response.
  @param[in]  Property           Further definition of information.

  @param[out] MoreData           Flag to indicate if there are more values of this type.
