drm/vc4: Add a paragraph at the top of vc4 docs introducing what it is. 



This makes for more sensible documentation of the whole module than
jumping straight into the details of display.

/**

 * DOC: Broadcom VC4 Graphics Driver

 *

 * The Broadcom VideoCore 4 (present in the Raspberry Pi) contains a

 * OpenGL ES 2.0-compatible 3D engine called V3D, and a highly

 * configurable display output pipeline that supports HDMI, DSI, DPI,

 * and Composite TV output.

 *

 * The 3D engine also has an interface for submitting arbitrary

 * compute shader-style jobs using the same shader processor as is

 * used for vertex and fragment shaders in GLES 2.0.  However, given

 * that the hardware isn't able to expose any standard interfaces like

 * OpenGL compute shaders or OpenCL, it isn't supported by this

 * driver.
