[PATCH v2 0/3] ppc: Enable 2nd DAWR support on Power10

[Ravi Bangoria]

This series enables 2nd DAWR support on p10 qemu guest. 2nd
DAWR is new watchpoint added in Power10 processor. Kernel/kvm
patches are already in[1].

Patches apply fine on qemu/master branch (9e2e9fe3df9f).

v1: 
https://lore.kernel.org/r/20200723104220.314671-1-ravi.bangoria@linux.ibm.com
[Apologies for long gap]
v1->v2:
  - Introduce machine capability cap-dawr1 to enable/disable
    the feature. By default, 2nd DAWR is OFF for guests even
    when host kvm supports it. User has to manually enable it
    with -machine cap-dawr1=on if he wishes to use it.
  - Split the header file changes into separate patch. (Sync
    headers from v5.12-rc3)
