NCR53C8XX: Remove deprecated IRQ flags (SA_*)
Stop using deprecated IRQ flags in ncr53c8xx documentaion. The new IRQF_* macros are used instead. Signed-off-by: Ahmed S.

ncr53c8xx=irqm:??, as follows:

a) If bit 0x10 is set in irqm, SA_SHIRQ flag is not used.

b) If bit 0x20 is set in irqm, SA_INTERRUPT flag is not used.

By default the driver uses both SA_SHIRQ and SA_INTERRUPT.

By default the driver uses both IRQF_SHARED and IRQF_DISABLED.

When an IRQ is shared by devices that are handled by different drivers, it

may happen that one driver complains about the request of the IRQ having

failed. Inder Linux-2.0, this may be due to one driver having requested the
