  firmware: arm_scmi: Fix deferred_tx_wq release on error paths (2022-11-01 11:36:20 +0000)

----------------------------------------------------------------
Arm SCMI fixes for v6.1

A bunch of fixes to handle:
1. A possible resource leak in scmi_remove(). The returned error
   value gets ignored by the driver core and can remove the device and
   free the devm-allocated resources. As a simple solution to be able to
   easily backport, the bind attributes in the driver is suppressed as
   there is no need to support it. Additionally the remove path is cleaned
   up by adding device links between the core and the protocol devices
   so that a proper and complete unbinding happens.
2. A possible spin-loop in the SCMI transmit path in case of misbehaving
   platform firmware. A timeout is added to the existing loop so that
   the SCMI stack can bailout aborting the transmission with warnings.
3. Optional Rx channel correctly by reporting any memory errors instead
   of ignoring the same with other allowed errors.
4. The use of proper device for all the device managed allocations in the
   virtio transport.
5. Incorrect deferred_tx_wq release on the error paths by using devres
   API(devm_add_action_or_reset) to manage the release in the error path.
