The STV0900 features two demodulator paths in one chip. Thus it is not
possible to use the generic power off function of the chip when sending
one of them to standby. The other path will stop working in that case.

The sleep function now switches off functionality specific to the demod
path. The global stuff is only switched off, when both paths are in
sleep mode. The wakeup function always turns on the global functionality
and then works specific to the path.

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.

Horizontal and vertical scaling range are according to the following equations.
If (SRC_Width >= 64 x DST_Width) { Exit(-1);  /* Out of Horizontal scale range}
If (SRC_Height >= 64 x DST_Height) { Exit(-1);  /* Out of Vertical scale range}

fimc_check_scaler_ratio() is used to check if horizontal and vertical
scale range are valid or not. To use fimc_check_scaler_ratio,
source and destination format should be set by VIDIOC_S_FMT.
And in case of scaling up, it doesn't have to check the scale range.

The main scaler has four SFRs for main scaler ratio depending on FIMC version.
FIMC 4.x has only two SFRs and FIMC 5.x has four SFRs for main scaler.
Those are MainHorRatio, MainHorRatio_ext, MainVerRatio and MainverRatio_ext.

The FIMC 5.x has 15 bit resolution for scaling ratio as below.
{MainHorRatio,MainHorRatio_ext} = {[14:6],[5:0]}.
{MainVerRatio,MainVerRatio_ext} = {[14:6],[5:0]}.
MainHorRatio = CISCCTRL[24:16], MainHorRatio_ext = CIEXTEN[15:10]
MainVerRatio = CISCCTRL[8:0],   MainVerRatio_ext = CIEXTEN[5:0]

This patch supports FIMC 4.x and FIMC 5.x using platform_device_id::driver_data.
