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.

Newer Loongson-3 will fix these issues and no workarounds are needed.

Say Y, unless you know what you are doing.

The workarounds have no significant side effect on them but may

decrease the performance of the system so this option should be

disabled unless the kernel is intended to be run on old systems.

If unsure, please say Y.
