[PATCH 14/22] drm/sun4i: Use simple encoder

[kbuild test robot]

Hi Thomas,

I love your patch! Yet something to improve:

[auto build test ERROR on next-20200305]
[cannot apply to rockchip/for-next shawnguo/for-next sunxi/sunxi/for-next tegra/for-next linus/master v5.6-rc4 v5.6-rc3 v5.6-rc2 v5.6-rc4]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
