drm/bridge: analogix_dp: some rockchip chips need to flip REF_CLK bit setting
As vendor document indicate, when REF_CLK bit set 0, then DP phy's REF_CLK should switch to 24M source clock. But due to IC PHY layout mistaken, some chips need to flip this bit(like RK3288), and unfortunately they didn't indicate in the DP version register. That's why we have to make this little hack.
