Icenowy Zheng a43a42ad9c drm/sun4i: add a Kconfig option for sun4i-backend
As sun4i-backend is now a dedicated module, add an Kconfig option for
it to make it optional, since some build may only use other engines.

Choose this option if you have an Allwinner SoC with the
original Allwinner Display Engine, which has a backend to
do some alpha blending and feed graphics to TCON. If M is
selected the module will be called sun4i-backend.
