Document the "rockchip,rk3568-edp" compatible. Like RK3576/RK3588,
the RK3568 eDP controller has the dp/pclk/hclk clocks and dp/apb
resets, but unlike them it does not use GRF registers, so make the
"rockchip,grf" property conditional on the SoC.
Also document the optional avdd-0v9 and avdd-1v8 supplies, which are
needed by the RK3568 eDP controller.

Are these valid for other compatibles?
Got it. These properties are not required for other compatibles.
I will restrict them to the RK3568 compatible in v4.
Best regards,
Damon
