The only time we transfer data (rather than issuing a command) out
of the AP->command TX endpoint is when we're clearing the hardware
pipeline. All that's needed is a "small" data buffer, and its
contents aren't even important.
For convenience, we just transfer a command structure in this case
(it's already mapped for DMA). The TRE is added to a transaction
using ipa_cmd_ip_tag_status_add(), but we ignore the size value
provided to that function. So just get rid of the size argument.
