mips: remove reference to "newer Loongson-3"
Newest Loongson-3 processors have moved to use LoongArch architecture. Sadly, the LL/SC issue is still existing on both latest Loongson-3 processors using MIPS64 (Loongson-3A4000) and LoongArch (Loongson-3A5000). As it's very unlikely there will be new Loongson-3 processors using MIPS64, let's stop people from false hoping.

Loongson-3 processors have the llsc issues which require workarounds.
Without workarounds the system may hang unexpectedly.
- Newer Loongson-3 will fix these issues and no workarounds are needed.
