media: dt-bindings: samsung,exynos4212-is: convert to dtschema

Convert the Samsung Exynos4212/4412 SoC Imaging Subsystem (FIMC-IS)
bindings to DT schema.  Changes during conversion - adjust to existing
DTS and Linux driver: add iommus and power-domains.

-Exynos4x12 SoC series Imaging Subsystem (FIMC-IS)
-
-The FIMC-IS is a subsystem for processing image signal from an image sensor.
-The Exynos4x12 SoC series FIMC-IS V1.5 comprises of a dedicated ARM Cortex-A5
-processor, ISP, DRC and FD IP blocks and peripheral devices such as UART, I2C
-and SPI bus controllers, PWM and ADC.
-
-fimc-is node
-------------
-
-Required properties:
-- compatible	: should be "samsung,exynos4212-fimc-is" for Exynos4212 and
-		  Exynos4412 SoCs;
-- reg		: physical base address and length of the registers set;
-- interrupts	: must contain two FIMC-IS interrupts, in order: ISP0, ISP1;
-- clocks	: list of clock specifiers, corresponding to entries in
-		  clock-names property;
-- clock-names	: must contain "ppmuispx", "ppmuispx", "lite0", "lite1"
-		  "mpll", "sysreg", "isp", "drc", "fd", "mcuisp", "gicisp",
-		  "pwm_isp", "mcuctl_isp", "uart", "ispdiv0", "ispdiv1",
-		  "mcuispdiv0", "mcuispdiv1", "aclk200", "div_aclk200",
-		  "aclk400mcuisp", "div_aclk400mcuisp" entries,
-		  matching entries in the clocks property.
-pmu subnode
------------
-
-Required properties:
- - reg : must contain PMU physical base address and size of the register set.
-
-The following are the FIMC-IS peripheral device nodes and can be specified
-either standalone or as the fimc-is node child nodes.
-
-i2c-isp (ISP I2C bus controller) nodes
-------------------------------------------
-
-Required properties:
-
-- compatible	: should be "samsung,exynos4212-i2c-isp" for Exynos4212 and
-		  Exynos4412 SoCs;
-- reg		: physical base address and length of the registers set;
-- clocks	: must contain gate clock specifier for this controller;
-- clock-names	: must contain "i2c_isp" entry.
-
-For the above nodes it is required to specify a pinctrl state named "default",
-according to the pinctrl bindings defined in ../pinctrl/pinctrl-bindings.txt.
-
-Device tree nodes of the image sensors' controlled directly by the FIMC-IS
-firmware must be child nodes of their corresponding ISP I2C bus controller node.
-The data link of these image sensors must be specified using the common video
-interfaces bindings, defined in video-interfaces.txt.
