[POWERPC] spufs: don't touch suspend bits when purging DMA queue
When we issue a MFC purge request, we may inadvertantly clear the suspended status. This change adds the MFC_CNTL_SUSPEND_MASK when we issue a purge request, so that the suspend bit is masked out. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
