Also fixed a memory leak in the probe function if an error occurred.
The gain control range was also fixed (a proper range from -64 to 64).

When a device is not detected, the driver prints a warning message.
That's ok, except for the fact that, even on newer devices that have
eeprom but aren't yet supported, it prints a message saying that the
device doesn't have eeprom.
Fix it by having a separate message for devices with eeprom, but not
yet known by the driver.

This driver is abusing the kernel<=>userspace API, due to the lack of a
proper solution for it. A discussion were done at:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg22196.html
But there's not a solution for it yet. So, move the driver to staging, while
we don't have a final solution.

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.

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

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 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]
