sna: Tune cache size for cpu bo cache

This helps SNB on cairo-traces that utilize lots of temporary uploads
(rasterised sources and masks for instance), but comes at a cost of
regressing others...

In order to counter the regression from increasing the GTT cache size,
the CPU/GTT vma cache are split and accounted separately.
