[ Upstream commit 85d2a31fe4d9be1555f621ead7a520d8791e0f74 ]
In all known platforms the ISP has dedicated IRQ lines, but for some reason the driver uses IRQF_SHARED.
Supporting IRQF_SHARED properly requires handling interrupts even when our device is disabled, and the driver does not handle this. To avoid adding such code, and to be sure the driver won't accidentally be used in a platform with shared interrupts, let's drop the IRQF_SHARED flag.
