drivers: video: add arducam camera driver

The Arducam mega is a low power, rolling shutter camera, supports
connecting one or more cameras to any microcontroller. It provides
high-quality image capture and processing capabilities, making it
highly suitable for various application fields, including machine
vision, image recognition, and robotics, among others. In current
implementation connecting multiple instances of the same camera
system is problematic.
