msm: mdss: do not resynchronize DSI FIFO if during device boot up

Browse source 
For PHY version 0x3, DSI FIFO needs to be resynchronized once DSI
PLL is enabled. But during device boot up if continuous splash is
enabled then we don't need to toggle the FIFO resync bit, since DSI
PLL will be already enabled by UEFI. So avoid toggling FIFO resync
if continuous splash is enabled.
