  Routine Description:
    Retrieves a Unicode string that is the user readable name of the EFI Driver.

  Arguments:
    This       - A pointer to the EFI_COMPONENT_NAME2_PROTOCOL instance.
    Language   - A pointer to a Null-terminated ASCII string array indicating the 
                 language.  This is the language of the driver name that the caller 
                 is requesting, and it must match one of the languages specified in 
                 SupportedLanguages. The number of languages supported by a 
                 driver is up to the driver writer.  Language is specified in RFC 
                 4646 language code format.
    DriverName - A pointer to the Unicode string to return.  This Unicode string
                 is the name of the driver specified by This in the language 
                 specified by Language.

  Returns:
    EFI_SUCCESS           - The Unicode string for the Driver specified by This
                            and the language specified by Language was returned 
                            in DriverName.
    EFI_INVALID_PARAMETER - Language is NULL or DriverName is NULL.
    EFI_UNSUPPORTED       - The driver specified by This does not support the 
                            language specified by Language.

  Routine Description:
    Retrieves a Unicode string that is the user readable name of the controller
    that is being managed by an EFI Driver.

  Arguments:
    This             - A pointer to the EFI_COMPONENT_NAME2_PROTOCOL instance.
    ControllerHandle - The handle of a controller that the driver specified by 
                       This is managing.  This handle specifies the controller 
                       whose name is to be returned.
    ChildHandle      - The handle of the child controller to retrieve the name 
                       of.  This is an optional parameter that may be NULL.  It 
                       will be NULL for device drivers.  It will also be NULL 
                       for a bus drivers that wish to retrieve the name of the 
                       bus controller.  It will not be NULL for a bus driver 
                       that wishes to retrieve the name of a child controller.
    Language         - A pointer to a Null-terminated ASCII string array indicating the 
                       language.  This is the language of the driver name that the caller 
                       is requesting, and it must match one of the languages specified in 
                       SupportedLanguages. The number of languages supported by a 
                       driver is up to the driver writer.  Language is specified in RFC 
                       4646 language code format.
    ControllerName   - A pointer to the Unicode string to return.  This Unicode
                       string is the name of the controller specified by 
                       ControllerHandle and ChildHandle in the language specified
                       by Language from the point of view of the driver specified
                       by This. 

  Returns:
    EFI_SUCCESS           - The Unicode string for the user readable name in the 
                            language specified by Language for the driver 
                            specified by This was returned in DriverName.
    EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE; ChildHandle 
                            is not NULL and it is not a valid EFI_HANDLE;Language 
                            is NULL;ControllerName is NULL.
    EFI_UNSUPPORTED       - The driver specified by This is not currently managing 
                            the controller specified by ControllerHandle and 
                            ChildHandle;The driver specified by This does not support the 
                            language specified by Language.
