spi/fsl-espi: Don't spin forever on SPIE_RXCNT
Infinite loop on SPIE_RXCNT occurred. while (SPIE_RXCNT(events) < min(4, mspi->len)) { cpu_relax(); events = mpc8xxx_spi_read_reg(&reg_base->event); } We met a soft lockup at fsl_espi_cpu_irq() because of this. Fix it by using spin_event_timeout() so that fsl_espi_cpu_irq() can break loop with timeouts dmesg.
