Camera: Bump camera splitter output slots

Currently we are configuring the number of output
slots in each new shared surface as the sum between the
maxiumum stream buffers and the minimum undequeued buffers
per surface. However the total number of buffers that
will get allocated in the input stream queue increases
with the latter undequeued ammount on each new output.
The delta between these values could result in
insufficient output slots for some outputs that consume
buffers with vastly different speeds combined with a
slow camera producer that exhausts all dequeued slots.
To avoid this set the output slot count the the maximum
supported number by the framework. Allocation is disabled
so this should not increase the number of allocated buffers.
