Hyunwoong Kim 5bbe425e57 [media] s5p-fimc: fix MSCTRL.FIFO_CTRL for performance enhancement
This patch fixes the value of FIFO_CTRL in MSCTRL.
Main-scaler has the value to specify a basis FIFO control of input DMA.

The description of FIFO_CTRL has been changed as below.
0 = FIFO Empty (Next burst transaction is possible when FIFO is empty)
1 = FIFO Full (Next burst transaction is possible except Full FIFO)

Value '1' is recommended to enhance the FIMC operation performance.
