firmware: arm_scmi: Add priv parameter to scmi_rx_callback
Add a new opaque void *priv parameter to scmi_rx_callback which can be
optionally provided by the transport layer when invoking scmi_rx_callback
and that will be passed back to the transport layer in xfer->priv.
This can be used by transports that needs to keep track of their specific
data structures together with the valid xfers.
