[PATCH v2] dt-bindings: rtc: add olpc,xo1-rtc to trivial-rtc

[Anushka Badhe]

Add the OLPC XO-1 RTC compatible string to the trivial-rtc schema
instead of creating a standalone binding file, as it only requires
a compatible property with no additional configuration.

Signed-off-by: Anushka Badhe <anushkabadhe@xxxxxxxxx>

Changes in v2:
- Move binding to trivial-rtc.yaml instead of separate file

Note:
* This patch is part of the GSoC2026 application process for device tree 
bindings conversions
