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.
