Commit Message

  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.

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.
