Currently there is a v4l2_device instance being registered per each
(capture and memory-to-memory) video node created per FIMC H/W instance.
This patch is a prerequisite for using the top level v4l2_device
instantiated by the media device driver.
To retain current debug trace semantic (so it's possible to distinguish
between the capture and m2m FIMC) the video_device is used in place
of v4l2_device where appropriate.

Add runtime PM and system sleep support in the memory-to-memory
driver. It's required to enable the FIMC operation on Exynos4
SoCs. This patch prevents system boot failure when the driver
is compiled in, as it now tries to access its I/O memory without
first enabling the corresponding power domain.
The camera capture device suspend/resume is not fully covered,
the capture device is just powered on/off during the video
node open/close. However this enables it's normal operation
on Exynos4 SoCs.

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.

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.
