i2c: i2c-ocores: DT bindings and minor fixes.
Cleanups to i2c-cores, no change in logic, changes are: * Move i2c-ocores device tree documentation from source file to Documentation/devicetree/bindings/i2c/i2c-ocores.txt. * Add \n to dev_warn and dev_err messages where missing * Minor updates to the text and formatting fixes.

+Device tree configuration for i2c-ocores
+
+Required properties:
+- compatible : "opencores,i2c-ocores"
+- reg : bus address start and address range size of device
+- interrupts : interrupt number
+- regstep : size of device registers in bytes
+- clock-frequency : frequency of bus clock in Hz
+- #address-cells : should be <1>
+- #size-cells : should be <0>
+
+Example:
+
+ i2c0: ocores@a0000000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "opencores,i2c-ocores";
+ reg = <0xa0000000 0x8>;
+ interrupts = <10>;
+ regstep = <1>;
+ clock-frequency = <20000000>;
+
+ dummy@60 {
+ compatible = "dummy";
+ reg = <0x60>;
+ };
+ };
