The SPI irq event will use to complete the SPI work in the SPI DMA mode,
so this patch is a preparation for the following DMA mode support.
Moreover the SPI interrupt can be fired when removing the SPI controller,
so we should make sure the SPI controller has stopped the queue in
remove function before freeing the SPI irq.

The __exit section is left out for built-in drivers, so a
'remove' callback must not be marked as such to avoid breaking when
we unbind a device at runtime. This was pointed out by kbuild:
`sprd_spi_remove' referenced in section `.data' of drivers/spi/spi-sprd.o: defined in discarded section `.exit.text' of drivers/spi/spi-sprd.o
