[PATCH v3 1/3] drm: add SimpleDRM driver

The SimpleDRM driver binds to simple-framebuffer devices and provides a DRM/KMS API. It provides only a single CRTC+encoder+connector combination plus one initial mode. Userspace can create dumb-buffers which can be blit into the real framebuffer similar to UDL. No access to the real framebuffer
