TLK sends the "preempted" event to the NS world along with an
identifier for certain use cases. The NS world driver is then
expected to take appropriate action depending on the identifier
value. Upon completion, the NS world driver then sends the
results to TLK (via x1-x3) with the TLK_RESUME_FID function ID.

This patch uses the already present code to pass the results
from the NS world to TLK for the TLK_RESUME_FID function ID.
