Subject: [PATCH v2 17/26] arm64: dts: allwinner: a64: Add HDMI support

HDMI on Allwinner A64 has similar behaviour like H3/H5/A83T, so
reuse the same dts node details for A64 with A83T compatible
as fallback.

HDMI PHY on Allwinner A64 has two clock parents so add them
as pll-0 and pll-1 in CCU clock phadles.
