tcg: Remove TCG_TARGET_STACK_GROWSUP
The hppa host code has been removed since 2013; this should have been deleted at the same time. Fixes: 802b5081233a ("tcg-hppa: Remove tcg backend") Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
