sky2: Avoid allocating memory in sky2_resume
Allocating memory can fail, and since we have the memory we need in sky2_resume when sky2_suspend is called, just stop the hardware without freeing the memory it's using. This avoids the possibility of failing because we can't allocate memory in sky2_resume(), and allows sharing code with sky2_restart().
