sim/erc32: Insert void parameter

Clang generates a warning if there is a function declaration/definition
with zero arguments.  Such declarations/definitions without a prototype (an
argument list) are deprecated forms of indefinite arguments
("-Wdeprecated-non-prototype").  On the default configuration, it causes a
build failure (unless "--disable-werror" is specified).

This commit replaces () with (void) to avoid this warning.
