The MUSB driver does not currently implment suspend/resume callbacks, seemingly because it does not support cutting power when devices are connected in host mode. Without a proper suspend/resume implementation, the OMAP PM domain layer which automatically gates non runtime-suspended devices will cause problems in suspend by the drivers ->runtime_suspend() callback which will try to cut power. Fix this by disabling PM domain auto suspending for MUSB until the driver can be fixed to properly implement suspend/resume.
