Until now, if there is a read error in tda18271_get_id, the driver
reports "Unknown device..."  Instead, check the return value of
tda18271_read_regs and display the appropriate error message.

if the configuration option 'delay_cal' is set, delay both IR & RF
calibration until init() is called.
both module option 'cal' or configuration option 'rf_cal_on_startup'
will override this delay. it makes no sense to mix 'delay_cal' with
'rf_cal_on_startup' as these options conflict with each other.

The mixer video node supports only multi-planar API so the driver
should not be setting V4L2_CAP_VIDEO_OUTPUT flags. Fix this and
also switch to device_caps. Additionally fix the VIDIOC_ENUM_FMT
ioctl handler which now works for V4L2_BUF_TYPE_CAPTURE, rather
than expected V4L2_BUF_TYPE_CAPTURE_MPLANE.

the crop operations are called directly for some reason in kernel

In order to reuse the FIMC-LITE module on Exynos4 and Exynos5
SoC introduce a set of callbacks for the media pipeline control
from within FIMC/FIMC-LITE video node. It lets us avoid symbol
dependencies between FIMC-LITE and the whole media device driver,
which simplifies the initialization sequences and doesn't
introduce issues preventing common kernel image for exynos4 and
exynos5 SoCs.
This patch also corrects following build errors:
drivers/built-in.o: In function `buffer_queue':
drivers/media/video/s5p-fimc/fimc-lite.c:414: undefined reference
to `fimc_pipeline_s_stream'
