linux: Release v4.4.17-openpower1

Upstream 4.4.17 stable release.

Aslo adds a patch from Mamatha for changing the VGA ownership register
value to fix slow BMC SOL. Note that it is unclear as to why this patch
fixes the issue. However, it has been requested that we include it so
here it is.

 We can't halt the secondary HCD, because it's also the primary HCD,
 which will cause problems if we have devices attached to the primary
