media: rkisp1: Drop IRQF_SHARED
[ 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.
