firmware: stratix10-svc: Add mutex in stratix10 memory management

Browse source

commit 85f96cbbbc upstream.

Add mutex lock to stratix10_svc_allocate_memory and
stratix10_svc_free_memory for thread safety. This prevents race
conditions and ensures proper synchronization during memory operations.
This is required for parallel communication with the Stratix10 service
channel.
