msm: mdss: send dcs command through dsi-1 only when roi-merge enabled

Browse source 
DSi-1 is responsible for triggering both controllers to send
dcs command to both panels at same time when sync-wait-broadcast
enabled. Therefore 2A/2B dcs command need to be sent to panels
through dsi-1 when both roi-merge and sync-wait-broadcast enabled.
