Subject: [PATCH] GameSettings: Add patch for Dead to Rights audio

This game follows the anti-pattern of calling memset on a buffer in the
midst of being DMA copied to ARAM, then calling a DVD read function that
effectively cancels the memset with dcbi instructions. Dolphin does not
emulate dcache for performance reasons, so this patch removes the
offending memset call.

Patches are included for two regions and are enabled by default.
