spi: fsl-espi: Only process interrupts for expected events
[ Upstream commit b867eef4 ] The SPIE register contains counts for the TX FIFO so any time the irq handler was invoked we would attempt to process the RX/TX fifos. Use the SPIM value to mask the events so that we only process interrupts that were expected. This was a latent issue exposed by commit 3282a3da ("powerpc/64: Implement soft interrupt replay in C").
