Fix it by or'ing WQ_SYSFS into @flags so that it actually enables sysfs interface and using 0 for @max_active for the default setting.

Such pools, though, are allocated globally to be used by the whole SCMI instance, they are not allocated per-channel and as such the allocation of notifications xfers cannot be simply skipped if no Rx channel was found for the base protocol common channel, because there could be defined more optional per-protocol dedicated channels that instead support Rx channels. Change the conditional check to skip allocation for the notification pool only if no Rx channel has been detected on any per-channel protocol at all.

Add more strict checking of SCMI mailbox transport device node descriptors.

This behaviour enables the system to boot with a broken regular SCMI stack but with a fully functional and accessible SCMI raw debugfs interface that can be used to further debug the issue.
