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.
