[ Upstream commit baf5cb30fbd1c22f6aa03c081794c2ee0f5be4da ]

On RM400(a20r) machines ISA and SCSI interrupts share the same interrupt
line. Commit 49e6e07e3c80 ("MIPS: pass non-NULL dev_id on shared
request_irq()") accidently dropped the IRQF_SHARED bit, which breaks
registering SCSI interrupt. Put back IRQF_SHARED and add dev_id for
ISA interrupt.

Fixes: 49e6e07e3c80 ("MIPS: pass non-NULL dev_id on shared request_irq()")
