If you look closer into the skipped part you'll see
// 13. Enable host interrupts (EHostIntEnable1 = KIrqReady |
KIrqWrReady | KHwUpdate | KSwUpdate)
TempReg = (SPI_HOST_INT_READY | SPI_HOST_INT_UPDATE |
SPI_HOST_INT_SW_UPDATE| SPI_HOST_INT_WR_READY);
SPIDRVWriteReg32(SPI_ADRS_HOST_INT_EN, TempReg);
which actually enables interrupts, exactly as SPI_IRQ(ENABLE); does.
