[media] marvell-cam: Move cafe-ccic into its own directory This driver will soon become a family of drivers, so let's give it its own place to live.

media: marvell-ccic: provide a clock for the sensor The sensor needs the MCLK clock running when it's being probed. On platforms where the sensor is instantiated from a DT (MMP2) it is going to happen asynchronously. Therefore, the current modus operandi, where the bridge driver fiddles with the sensor power and clock itself is not going to fly. As the comments wisely note, this doesn't even belong there. Luckily, the ov7670 driver is already able to control its power and reset lines, we can just drop the MMP platform glue altogether. It also requests the clock via the standard clock subsystem. Good -- let's set up a clock instance so that the sensor can ask us to enable the clock. Note that this is pretty dumb at the moment: the clock is hardwired to a particular frequency and parent.

[media] marvell-cam: convert to videobuf2 This is a basic, naive conversion to the videobuf2 infrastructure, removing a lot of code in the process. For now, we're using vmalloc, which is suboptimal, but it does match what the cafe driver did before. In the cafe case, it may have to stay that way just because memory is too tight to do direct streaming; mmp-camera will be able to do better.

This is a video4linux2 driver for the Marvell 88ALP01 integrated
CMOS camera controller. This is the controller found on first-
generation OLPC systems.

processors (and likely beyond). This is the controller found
in OLPC XO 1.75 systems.
