dt-bindings: rtc: Split loongson,ls2x-rtc into SoC-based compatibles 



Move Loongson RTC bindings from trivial-rtc.yaml into loongson,rtc.yaml.

The architectures associated with this driver use the built-in DTB, so
we can just drop the compatible(rtc-ls2x) with wildcards.
Also, soc-based compatible is more accurate for hardware differences
between chips.
