refactor(spmd): move plat_my_core_pos calls

By tracing instruction execution, it is observed:
Placing plat_my_core_pos at top of functions translate by the compiler
into calling those functions even if the result is not consumed when not
printed.
plat_my_core_pos is used to retrieve the core id for the currently
running core, but effectively call sites are only consuming it for
verbosity purposes. Move plat_my_core_pos calls into the print functions
that require it.
