media: imx: imx8mq-mipi-csi2: remove wrong irq config write operation
[ Upstream commit 59c2b6d51803ad6b7af28f2a60a843b24374e692 ]
The place where this register writel() that masks one interrupt is placed
does not guarantee that the device is powered so that's not allowed.
Moreover imx8mq_mipi_csi_start_stream() masks the interrupt anyway so the
write is not even needed. Remove it as this is a mistake that slipped in
with the driver.
