Dolby: garbage images on screen when output 720 [1/1]

PD#SWPL-9805

Problem:
dolby graphics core setting is marginal at 720@50 or 720@60

Solution:
Leave more margin in vertical potch for graphic core
Another modification: force update core2 and core3 reg
when dolby-vision on

Verify:
local build test on dolby tv 720@50/720@60/1080p24hz
