Kees Cook 7ba59ac7da greybus: Avoid fake flexible array for response data 
FORTIFY_SOURCE has been ignoring 0-sized destinations while the kernel
code base has been converted to flexible arrays. In order to enforce
the 0-sized destinations (e.g. with __counted_by), the remaining 0-sized
destinations need to be handled. Instead of converting an empty struct
into using a flexible array, just directly use a pointer without any
additional indirection. Remove struct gb_bootrom_get_firmware_response
and struct gb_fw_download_fetch_firmware_response.

* (0x80) of the operation type field is used to indicate whether
* the message is a request (clear) or a response (set).
*
* Response messages include an additional result byte, which
* communicates the result of the corresponding request. A zero
