[PATCH Resend 1/2] amba: Kill sysfs attribute file of irq

From: Kefeng Wang
Date: Mon Nov 15 2021 - 08:42:52 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.
