Subject: [PATCH 0/7] powerpc/watchpoint: Enable 2nd DAWR on baremetal and powervm

Last series[1] was to add basic infrastructure support for more than
one watchpoint on Book3S powerpc. This series actually enables the 2nd
DAWR for baremetal and powervm. Kvm guest is still not supported. This
series depends on Alistair's "Base support for POWER10"[2] series.
