dt-bindings: display: sun6i-dsi: Add the A100 variant

The "40nm" MIPI DSI controller found in the A100 and D1 SoCs has the
same register layout as previous SoC integrations. However, its module
clock now comes from the TCON, which means it no longer runs at a fixed
rate, so this needs to be distinguished in the driver.

The controller also now uses pins on Port D instead of dedicated pins,
so it drops the separate power domain.
