The upcoming writeback feature of the VSP1 WPF, allows the active output
of the DU to be written back to memory. On Generation 3 hardware, the DU
is fed by the LIF, which is in turn fed by the WPF.
It is the WPF which will perform memory writeback functionality, and
this brings in a second output of the entity. Configured in this mode,
the WPF will output to both the LIF, and to a memory (V4L2 video)
device.
Support this feature by extending vsp1_entity_init() to specify the
number of source and sink pads.
