[media] exynos4-is: Use external s5k6a3 sensor driver
This patch removes the common fimc-is-sensor driver for image sensors
that are normally controlled by the FIMC-IS firmware. The FIMC-IS
driver now contains only a table of properties specific to each sensor.
The sensor properties required for the ISP's firmware are parsed from
device tree and retrieved from the internal table, which is selected
based on the compatible property of an image sensor.
To use the Exynos4x12 internal ISP the S5K6A3 sensor driver (drivers/
media/i2c/s5k6a3.c) is now required.

[media] V4L: Add driver for s5k6a3 image sensor
This patch adds subdev driver for Samsung S5K6A3 raw image sensor.
As it is intended at the moment to be used only with the Exynos
FIMC-IS (camera ISP) subsystem it is pretty minimal subdev driver.
It doesn't do any I2C communication since the sensor is controlled
by the ISP and its own firmware.
This driver, if needed, can be updated in future into a regular
subdev driver where the main CPU communicates with the sensor
directly.

devicetree binding:
- addition of #clock-cells and clock-output-names properties to 'camera'

clocks provided by the camera host interface,
- dropped a note about required clock-frequency properties at the
image sensor nodes; the sensor devices can now control their clock
explicitly through the clk API and there is no need to require this

Add volatile boolean control to indicate if tuner frequency synthesizer

given frequency. Control is named as "PLL lock", since frequency
synthesizers are based of phase-locked-loop. Maybe more general name
could be wise still?

When either of the normal or wakeup filter protocols are changed,
refresh the corresponding scancode filter, i.e. try and set the same

instead.
If no protocol was selected the filter is just cleared, and if no
s_filter callback exists the filter is left unmodified.
Similarly clear the filter mask when the filter is set if no protocol is
currently selected.
This simplifies driver code which no longer has to explicitly worry
about modifying the filter on a protocol change. This also allows the
change_wakeup_protocol callback to be omitted entirely if there is only
a single available wakeup protocol at a time, since selecting no
protocol will automatically clear the wakeup filter, disabling wakeup.
