Commit a81068181a ("media: move CEC USB drivers to a separate directory")
moved drivers/media/usb/{pulse8,rainshadow}-cec to
drivers/media/cec/usb/{rainshadow,pulse8}, but did not adjust the entries
in MAINTAINERS.
Since then, ./scripts/get_maintainer.pl --self-test=patterns complains:
warning: no file matches F: drivers/media/usb/pulse8-cec/*
warning: no file matches F: drivers/media/usb/rainshadow-cec/*
Update the MAINTAINERS entries to the new file locations.

The colorspace reported by a video nodes should not be
V4L2_COLORSPACE_DEFAULT. Instead a default colorspace should be picked
by the driver if V4L2_COLORSPACE_DEFAULT is given by userspace to
{G,S,TRY}_FMT.
The colorspace V4L2_COLORSPACE_SRGB is arbitrary chosen as the vimc
default format to report as it's used for most webcams.

Some media entry attributes got out of the order after the
bug was split into 3. Also, as reported by Johan, the
Rockchip VPU entry also had their attributes at the wrong
order.
As those entries weren't merged yet upstream, let's reorder
them with:

The USB_DEVICE() list contain some of the product names, but
some are missing, and others are different than the message
printed during device detection.

device.

Instead of using USB_DEVICE() macro directly, use the
DVB_USB_DEVICE() one, as other dvb-usb-v2 devices.
The usage of the new macro makes cleaner and easier to
parse the supported device names in a way that it would
be easily parseable to generate cardlists.
