hw/ppc/virtex_ml507: Drop use of ppcuic_init()
Switch the virtex_ml507 board to directly creating and
configuring the UIC, rather than doing it via the old
ppcuic_init() helper function.
This fixes a trivial Coverity-detected memory leak where
we were leaking the array of IRQs returned by ppcuic_init().
Fixes: Coverity CID 1421992
