target/ppc: Add POWER9 external interrupt model
Adds support for the Hypervisor directed interrupts in addition to the
OS ones.
Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
[clg: - modified the icp_realize() and xive_tctx_realize() to take
into account explicitely the POWER9 interrupt model
- introduced a specific power9_set_irq for POWER9 ]
