Subject: [PATCH v2 06/12] media: imx-mipi-csis: Move irq flag and handler to
 mipi_csis_info structure

FSD CSI IP has only one IRQ line, shared between imx-mipi-csis and
fsd-csi-media drivers. To extend this driver for FSD SoC support,
move the IRQ flag and IRQ handler to the device data(structure
mipi_csis_info).
