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.

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.
