dt-bindings: rtc: imxdi: Improve the bindings text

Browse Source 
Improve the bindings text by doing the following changes:

- Remove the i.MX53 reference, as the RTC on i.MX53 is a different hardware
- Add 'clocks' to the list of required properties
- Explain that the optional security violation irq is the second entry
- Use the real unit address and irq numbers for i.MX25

* i.MX25 Real Time Clock controller
This binding supports the following chips: i.MX25, i.MX53
Required properties:
- compatible: should be: "fsl,imx25-rtc"
- reg: physical base address of the controller and length of memory mapped
region.
- clocks: should contain the phandle for the rtc clock
- interrupts: rtc alarm interrupt
Optional properties:
- interrupts: dryice security violation interrupt
- interrupts: dryice security violation interrupt (second entry)
Example:
rtc@80056000 {
compatible = "fsl,imx53-rtc", "fsl,imx25-rtc";
reg = <0x80056000 2000>;
interrupts = <29 56>;
rtc@53ffc000 {
compatible = "fsl,imx25-rtc";
reg = <0x53ffc000 0x4000>;
clocks = <&clks 81>;
interrupts = <25 56>;
};
