mips: remove reference to "newer Loongson-3"

Browse source 
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.

help
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.
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.
Say Y, unless you know what you are doing.
