V4L: Add driver for Samsung S5K8B1YX image sensor
This patch adds a stub driver for Samsung S5K8B2YX raw image sensor. There is currently no I2C communication done in this driver. It can be added if required. This driver was tested only with Exynos FIMC-IS subsystem (camera ISP), which communicates with the sensor over I2C bus in firmware.

+Samsung S5K8B1YX raw image sensor
+---------------------------------
+
+S5K8B1YX is a raw image sensor with MIPI CSI-2 image data interfaces and CCI
+(I2C compatible) control bus.
+
+Required properties:
+
+- compatible : "samsung,s5k8b1";
+- reg : I2C slave address of the sensor;
+- vdda-supply : analogue power supply (typically 2.8 V);
+- vddio-supply : digital I/O power supply (typically 1.8 V);
+- vddd-supply : digital core power supply (typically 1.2 V);
+- xshutdown-gpios : specifier of a GPIO connected to the XSHUTDOWN pin;
+- clocks : should contain the sensor's EXTCLK clock specifier, from
+ the common clock bindings.
+- clock-names : should contain "extclk" entry;
+- data-lanes : specifies MIPI CSI-2 data lanes as covered in
+ video-interfaces.txt. The sensor supports up to 2 data
+ lanes.
+
+Optional properties:
+
+- clock-frequency : the frequency at which the "extclk" clock should be
+ configured to operate, in Hz; if this property is not
+ specified default 24 MHz value will be used.
+
+The common video interfaces bindings (see video-interfaces.txt) should be
+used to specify link to the image data receiver. The S5K8B1YX device node
+should contain one 'port' child node with an 'endpoint' subnode.
