[PATCH v5 2/3] dts: allow to get multiple expected packets

[Luca Vizzarro <luca.vizzarro@arm.com>]

At the moment there is only one facility that allows to prepare a packet
as it is expected to be received on the traffic generator end. Extend
this to allow to prepare multiple packets at the same time.
