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.

The Image Sensing Interface (ISI) combines image processing pipelines

interfaces, and their number and nature is SoC-dependent. They cover
both capture interfaces (MIPI CSI-2 RX, HDMI RX) and memory inputs.

media: imx: Unstage the imx7-media-csi driver

The imx7-media-csi driver, currently in staging, is ready for
prime-time. The staging TODO file lists a few items specific to that
driver, that are already addressed (the "all of the above" part) or can
be addressed later:

- The frame interval monitoring support is a software mechanism to
monitor the device for unexpected stalls, and should be part of the
V4L2 core if desired.

- Restricting the support media bus formats based on the SoC integration
only aims at reducing userspace confusion by not enumerating options
that are known not to be possible, it won't cause regressions if
handled later.

Move the description of the media bus format restriction TODO item to
the driver, drop the other TODO items, and move the driver out of
staging.

media: dw100: Add i.MX8MP dw100 dewarper driver

Add a V4L2 mem-to-mem driver for the Vivante DW100 Dewarp Processor IP
core found on i.MX8MP SoC.

The processor core applies a programmable geometrical transformation on
input images to correct distorsion introduced by lenses.
The transformation function is exposed as a grid map with 16x16 pixel
macroblocks indexed using X, Y vertex coordinates.

The dewarping map can be set from application through a dedicated v4l2
control. If not set or invalid, the driver computes an identity map
prior to starting the processing engine.

The driver supports scaling, cropping and pixel format conversion.

media: Kconfig: cleanup VIDEO_DEV dependencies

media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.

On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
1) enable Video4Linux and make its Kconfig options to appear;
2) it makes the Kernel build the V4L core.

while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.

With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.

At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:

menu "Video4Linux options"
visible if VIDEO_DEV

source "drivers/media/v4l2-core/Kconfig"
endmenu

but it doesn't affect anymore the V4L core drivers.

The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:

config VIDEO_V4L2
tristate
depends on (I2C || I2C=n) && VIDEO_DEV
select RATIONAL
select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
default (I2C || I2C=n) && VIDEO_DEV

In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.

Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.
