tracing: Rename update_cache() to update_mod_cache()

tracing: Rename update_cache() to update_mod_cache()

The static function in trace_events.c called update_cache() is too generic
and conflicts with the function defined in arch/openrisc/include/asm/pgtable.h

Rename it to update_mod_cache() to make it less generic.
