target/hppa: Do not use hardcoded value for tlb_flush_*()

Avoid using hardcoded values when calling the tlb_flush*() functions. Instead, define and use HPPA_MMU_FLUSH_MASK (keeping the current behavior, which doesn't flush the physical address MMU). Signed-off-by: Helge Deller <deller@gmx.de> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org>
