The patch set includes the following changes:
- Add protection for querying memory objects in
multi-threaded flow.
- Add support to generate and maintain message id
and client id for asynchronous communication with SDM.
- Add framework to communicate with Secure Device
Manager(SDM) asynchronously by sending a request
and polling for response.
- Add interrupt definition in Agilex devicetree
for asynchronous communication.
- Add SDM interrupt support for Agilex platform
supporting asynchronous communication.
- Add support to optionally notify the clients if
response is available using interrupts from SDM.
- Add commands for querying temperature and voltage
from SDM.

Changes in v3:
- Changed "Stratix 10" to "Stratix10" in the commit
message and in source code.
- Simplified stratix10_svc_add_async_client() by removing
redundant code for async common channel initialization.
- Fixed resource cleanup on negative path in
stratix10_svc_remove_async_client() and stratix10_svc_async_init().
- Removed optional interrupt handler support, will send the patches
in a separate patch-set.
