Subject: [PATCH v2] media: imx: Unstage the imx8mq-mipi-csi2 driver

The imx8mq-mipi-csi2 MIPI CSI-2 receiver driver is used and maintained.
There is no reason to keep it in staging. The accompanying CSI bridge
driver that uses it is in drivers/media/platform/nxp as well.

One TODO is to get rid of csi_state's "state" and "lock" variables.
Especially make sure suspend/resume is working without them. That can
very well be worked on from the new location.

Also add a MAINTAINERS section for the imx8mq-mipi-csi2 mipi receiver
driver.

Thanks for reviewing Laurent,

Are there any second thoughts to this? If not: It still applies to
todays' next kernel. Who would be able to queue this up?

(This enables Debian and other distributions to use cameras on imx8mq.)

This still applies cleanly and would be helpful. Does anyone want to
queue this?
