The Qualcomm SM8450 platform comes with both some smaller changes in the
firmware packaging and a new requirement to hold onto the metadata buffer until
PAS auth_and_reset has been completed.

Extend the PAS api and rework the mdt_loader to meet these new requirements,
then wire this up with the PAS remoteproc driver and finally add the SM8450
remoteproc instances.

Minor nitpicks:
- I'd reorder the series by moving patch 1 (pas_metadata) closer to patch 8&9 (pas metadata usage)
- I would have added pas_metadata as an argument to qcom_mdt_load(). However I see, why you didn't want to add another argument to the list.
