dolphin-emu: add patch for soundtouch 2.1.2 and enable ppc64le

Technically this should also work on aarch64 but I haven't tested
that, so I'm not enabling it. Building for ppc64le as well as any
other little endian architecture requires a generic (architecture
independent) build to be enabled.

Also, add a patch to fix compilation with soundtouch 2.1.2. Also,
fix lint issues, and appropriately bump revision.
