[PATCH v4 07/14] clk: sunxi-ng: a523: add video mod clocks

[Andre Przywara <andre.przywara@arm.com>]

Add the clocks driving the various video subsystems of the SoC: the "DE"
display engine, the "DI" deinterlacer, the "G2D" 2D graphics system, the
Mali "GPU", the "VE" video engine, its associated IOMMU, as well as the
clocks for the various video output drivers (HDMI, DP, LCDs).
