[PATCH v3 2/7] eventdev: fix header build with C++

[Bruce Richardson]

The eventdev headers had issues when used from C++

* Missing closing "}" for the extern "C" block
* No automatic casting to/from void *

Fixes: a6562f6d6f8e ("eventdev: introduce event timer adapter")
Fixes: 32e326869ed6 ("eventdev: add tracepoints")
