Subject: [PATCH 2/3] drm/sun4i: change A64 HDMI PHY binding to R40

The Allwinner A64 SoC is proven to have no PLL-VIDEO mux in the HDMI PHY
clock, although it has two PLL-VIDEOs. The R40 SoC has this mux.

Change the binding compatible string from sun50i-a64 to sun8i-r40, and
let A64 to use H3 compatible string.

The compatible string is introduced in v4.19, and during the RC stage we
can still change it.
