media: imx-media-csc-scaler: Use a shorter name for driver

Currently v4l2-compliance tool returns the following output:

Compliance test for imx-media-csc-s device /dev/video8:

Driver Info:
        Driver name      : imx-media-csc-s
        Card type        : imx-media-csc-scaler
        Bus info         : platform:imx-media-csc-scaler

The driver name string is limited to 16 characters, so provide
a shorter name in order to get a better output.

While at it, use the same shorter name for driver, card and platform.
