sim: d10v: fix build warnings

The printf fix uses our PRIxTA for our sim address type.

Then cast away the const (since the underlying code safely treats it
as such) even if it's ugly.

Finally touch up the argv iterator pointer to match the new func arg.

With this tidied up, we can delete the SIM_AC_OPTION_WARNINGS(no) call
to get the default common behavior where -Werror is enabled.
