Expose the inherited properties from the base analogix-dp schema

Given it's unevaluatedProperties, not addtionalProperties, this patch
shouldn't be needed?
When I remove both the top-level data-lanes property and those explicit
"xxx: true" property entries and run the dtbs check with:
make CHECK_DTBS=y CROSS_COMPILE=aarch64-linux-gnu- LT0=none LLVM=1
LLVM_IAS=1 ARCH=arm64 rockchip/rk3588-evb1-v10.dtb
rockchip/rk3588s-evb1-v10.dtb rockchip/rk3399-sapphire-excavator.dtb
rockchip/rk3576-evb1-v10.dtb -j4
It results in validation errors like these:
/home/ding/drm-misc/arch/arm64/boot/dts/rockchip/rk3576-evb1-v10.dtb:
edp@27dc0000: ports:port@1:endpoint: Unevaluated properties are not

I suspect that the properties defined in the child binding are
overriding/masking all the inherited properties from the parent Analogix
DP schema.
Is there a better way to fix this issue without explicitly listing all
inherited properties as true?
Best regards,
Damon
