drm/i915: HSW always use GGTT selector for secure batches
gen6 and earlier conflate address space selection (ppgtt vs ggtt) with
the security bit (i.e. only privileged batches were allowed to run from
ggtt). From Haswell only, you are able to select the security bit
separate from the address space - and we always requested to use ppgtt.
This breaks the golden render state batch execution with full-ppgtt as
that is only present in the global GTT and more generally any secure
batch that is not colocated in the ppgtt and ggtt. So we need to
disable the use of the ppgtt selector bit for secure batches, or else we
hang immediately upon boot and thence after every GPU reset...
v2: Only HSW differentiates between secure dispatch and ggtt, so simply
ignore the differentiation and always use secure==ggtt.

The problem with the current implementation is that adding a timer improperly

time elapsed since their timer got scheduled. Rework the re-scheduling
decision t fix this.
The catch with this fix is that we are limited to scheduling timers of up to
2^31 ticks to avoid any potential overflow. Since we are unlikely to need to
wait for more than a second, this won't be a problem :)
Another possible fix would be to decrement the timeouts of all processes but
it would duplicate a lot of code and dealing with edge cases wasn't pretty
last time I checked.
