[PATCH v3 0/2] rtc: omap: update AM335x rtc ip revision

The syntax of compatible property in DT is to mention the Most specific
match to most generic match.

Since AM335x is the platform with latest IP revision, add it 1st in
the device id table.

This way, we can add new matching compatible as 1st and maintain old
compatible string for backwards compatibility.

ex:
compatible = "ti,am3352-rtc", "ti,da830-rtc";

Also, update am335x .dtsi file (am33xx.dtsi) as above.

Note:
This is a part of previously submitted patch-set [1]. Out of 4 patches,
3 was accepted and 1 got an acceptable NAK. Hence resubmitting only the
rejected + updated changes.

Changes in V3:
- As per Mark Rutland's suggestion [2], maintain old compatible
string and add the new matching string as the 1st compatible.

Changes in V2:
- Coding style corrections (remove extra space, use lower case
for hex numbers
- use prefix ARM: for commit subject keeping with arch/arm
convention)
- use "[AM/am]3352" instead of "[AM/am]335x" to keep the all
usages in sync.
- Use index defined for struct members so they remain in sync
- Add new compatible to existing one so that when driver
supports enhanced features of hardware, they are available
to the user else the basic functionality still works
