bindings: i2c: use consistent naming for i2c binding descriptions
Filenames of devictree binding documentation seems to be arbitrary and for me it is unneeded hazzle to find the corresponding documentation for a specific driver. Naming the description the same as the driver is a lot easier and makes sense to me since the driver defines the binding it understands. Also, remove a reference in one source to the binding documentation, since path information easily gets stale.

-Common i2c bus multiplexer/switch properties.
-
-An i2c bus multiplexer/switch will have several child busses that are
-numbered uniquely in a device dependent manner. The nodes for an i2c bus
-multiplexer/switch will have one child node for each child
-bus.
-
-Required properties:
-- #address-cells = <1>;
-- #size-cells = <0>;
-
-Required properties for child nodes:
-- #address-cells = <1>;
-- #size-cells = <0>;
-- reg : The sub-bus number.
-
-Optional properties for child nodes:
-- Other properties specific to the multiplexer/switch hardware.
-- Child nodes conforming to i2c bus binding
-
-
-Example :
-
- /*
- An NXP pca9548 8 channel I2C multiplexer at address 0x70
- with two NXP pca8574 GPIO expanders attached, one each to
- ports 3 and 4.
- */

- mux@70 {
- compatible = "nxp,pca9548";
