visium: Fix up visium_setup_incoming_varargs [PR114175]
Like for x86-64, alpha or rs6000, visium seems to be affected too.
Just visually checked differences in c23-stdarg-9.c assembly in a cross
without/with the patch, committed to trunk.

* config/visium/visium.cc (visium_setup_incoming_varargs): Only skip
TARGET_FUNCTION_ARG_ADVANCE for TYPE_NO_NAMED_ARGS_STDARG_P
functions
if arg.type is NULL.
