Boris Brezillon 988f259b46 spi: Add an helper to flush the message queue ...

This is needed by the spi-mem logic to force all messages that have been
queued before a memory operation to be sent before we start the memory
operation. We do that in order to guarantee that spi-mem operations do
not preempt regular SPI transfers.
