remoteproc/keystone: fix kernel crash with sysfs unbind and MPM loader The Keystone remoteproc driver supports two different load & boot mechanisms - the regular kernel space based loading and a userspace based Multi Proc Manager (MPM) loading. The driver has slightly different state machine flow between the two mechanisms. The standard platform driver's bind and unbind sysfs attributes can be used to boot and shutdown a Keystone DSP processor supporting remoteproc core's auto-boot. Suppress these attributes for MPM-based stack so that the sysfs approach does not mess up the MPM-based state-machine by unbinding the device from the driver even when it has open usage reference counts.
