ppc/pnv: Extend XiveRouter with a get_block_id() handler
When doing CAM line compares, fetch the block id from the interrupt controller which can have set the PC_TCTXT_CHIPID field. Signed-off-by: Cédric Le Goater <clg@kaod.org> Message-Id: <20191125065820.927-20-clg@kaod.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
