Release Linux 4.11.0-openpower1

New upstream release. This includes all of the patches we were carrying
aginst the Aspeed ast DRM driver.

We still carry three patches:

 - XCHI
   * xhci: do not halt the secondary HCD
   * xhci: Use xhci_pci_remove for xhci device shutdown
 - OPAL
  * powerpc/powernv: Add OPAL exports attributes to sysfs

The skiroot_p9 and skiroot defconifgs were regenerated against the
upstream kernel.
