Subject: [PATCH v3 4/7] media: imx-mipi-csis: Move irq flag and handler to
 mipi_csis_info structure

The Tesla FSD CSIS IP has single IRQ line, which is shared between
imx-mipi-csis and fsd-csis drivers. To extend this driver for Tesla FSD
SoC support, move the IRQ flag and IRQ handler into the device
data(structure mipi_csis_info).
