Add sam_linux_is_in_normal_world() which allows to know if Linux is
running in the normal world or not. This function is used by code
which needs to differentiate the world in which Linux is running.

In case optee hasn't been detected don't we run also in normal world?
What I want to say is that maybe you can change the function name to
something like sam_linux_is_optee_available().
