Add and document the reserved memory region property in the mdss-common schema.
For now (sdm845-db845c), it points to a framebuffer memory region reserved by the bootloader for splash screen.
Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Amit Pundir <amit.pundir@linaro.org> --- v6: Re-sending with review and ack tags. Ideally this dt-binding patch should be marked for stable as well, like the follow-up sdm845-db845c.dts patch in the series but it can't be cherry picked cleanly on older LTS versions. I can do it separately if it is required.
v5: Moving the dt-binding to mdss-common schema with updated commit message and property description.
v4: Adding this new dt-binding patch, in qcom,sdm845-mdss schema, in the v4 of the follow-up patch for sdm845-db845c. https://lore.kernel.org/lkml/20230712130215.666924-2-amit.pundir@linaro.org/
