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

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>;
 };
