Ondrej Zary 906e4a3c7e scsi: g_NCR5380: Use probe_irq_*() for IRQ probing
Use standard probe_irq_on() and probe_irq_off() functions instead of own
implementation.  This prevents warning messages like this in the kernel
log: genirq: Flags mismatch irq 1. 00000000 (NCR-probe) vs. 00000080
(i8042)

Move the IRQ trigger code from NCR5380 to g_NCR5380 where it is used.

Also clear interrupt flag before and after the probe.
