firmware: qcom: scm: Introduce pas_metadata context
Starting with Qualcomm SM8450, some new security enhancements has been
done in the secure world, which results in the requirement to keep the
metadata segment accessible by the secure world from init_image() until
auth_and_reset().
Introduce a "PAS metadata context" object that can be passed to
init_image() for tracking the mapped memory and a related release
function for client drivers to release the mapping once either
auth_and_reset() has been invoked or in error handling paths on the way
there.
