[PATCH 5.17 0300/1126] media: imx: imx8mq-mipi-csi2: remove wrong irq config write operation

[Greg Kroah-Hartman]

From: Martin Kepplinger <martin.kepplinger@xxxxxxx>

[ 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.

Fixes: f33fd8d77dd0 ("media: imx: add a driver for i.MX8MQ mipi csi rx phy and controller")
