Johan Hovold 2358024b67 greybus: control: suppress bundle_activate() for bootrom ... We always knew backward compatibility with the ES3 bootrom, which was finalised about a year ago, would be a pain. Here we go again. The bootrom does not support control requests added after it was burnt into ROM for obvious reasons. This means that we need to suppress sending the new bundle_activate() operation to any interface executing the legacy bootrom. Do so by adding a new NO_PM interface quirk (we can use the control-protocol version for this later once we bump it). Note that the interface-disable path (e.g. for power down) is already handled by the FORCED_DISABLE quirk, and that the suspend/resume paths are currently avoided by making sure that the bootrom bundle never suspends.
