irqchip/gic-v3-its: Flush ITS tables correctly in non-coherent GIC designs
In non-coherent GIC designs, the ITS tables must be flushed before writing
to the GITS_BASER<n> registers, otherwise the ITS could read dirty tables,
which results in unpredictable behavior.
Flush the tables right at the begin of its_setup_baser() to prevent that.
