[PATCH v2 3/4] amba: Kill sysfs attribute file of irq

From: Kefeng Wang
Date: Fri Aug 27 2021 - 11:02:27 EST


As Rob said[1], there doesn't seem to be any users about the sysfs
attribute file of irq[0] and irq[1]. And we don't need to include
<asm/irq.h> as NO_IRQ has gone. Let's kill both of them.
