Add tracepoints to retrieve information about the invoke_fn. This would help to measure how many invoke_fn are triggered and how long it takes to complete one invoke_fn call.

The problem also affects arm:imx_v6_v7_defconfig.
I think it affects everything. The problem is that the drivers/tee/optee/Makefile needs to be updated with:
CFLAGS_call.o := -I$(src)
otherwise the compiler wont know how to find the path to optee_tree.h.
This is described in:
samples/trace_events/Makefile
