[PATCH v5 1/2] dt-bindings: display/msm: mdss-common: add memory-region property

[Amit Pundir]

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.

    sdm845-db845c.
