Changelog v2:
 * Restore xirr_owner after migration
 * Call icp_resend after restoring all the ICP

Changelog v1:
 * Change XICS to XICS_SPAPR and KVM_XICS to XICS_KVM_SPAPR
 * Added xics_ to function get_cpu_index_by_dt_id as this is a global symbol
 * Dropped server parameter from  icp_check_ipi
 * Send HW_ERROR when ics is NULL
 * Remove redundant parameters in trace routines
