Wolfram Sang 16c4c52435 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.

* NXP PNX I2C Controller
Required properties:
- reg: Offset and length of the register set for the device
- compatible: should be "nxp,pnx-i2c"
- interrupts: configure one interrupt line
- #address-cells: always 1 (for i2c addresses)
- #size-cells: always 0
- interrupt-parent: the phandle for the interrupt controller that
services interrupts for this device.
Optional properties:
- clock-frequency: desired I2C bus clock frequency in Hz, Default: 100000 Hz
Examples:
i2c1: i2c@400a0000 {
compatible = "nxp,pnx-i2c";
reg = <0x400a0000 0x100>;
interrupt-parent = <&mic>;
interrupts = <51 0>;
#address-cells = <1>;
#size-cells = <0>;
};
i2c2: i2c@400a8000 {
compatible = "nxp,pnx-i2c";
reg = <0x400a8000 0x100>;
interrupt-parent = <&mic>;
interrupts = <50 0>;
#address-cells = <1>;
#size-cells = <0>;
clock-frequency = <100000>;
};
