msm: mdss: add DSI revision check for continuous splash screen

Browse source 
Handoff APIs tries to do clamp configuration during
continuous splash screen. This configuration is not
working for msm8996 which put PHY in bad state for
this target. It is fixed by adding the DSI revision
check in handoff API to avoid clamp configuration.
