Add thread safety to ECP hardware acceleration

The intended use of the abstraction layer for Elliptic Curve Point
arithmetic is to enable using hardware cryptographic accelerators.
These devices are a shared resource and the driver code rarely provides
thread safety.

This commit adds mutexes to the abstraction layer to protect the device
in a multi-threaded environment.
