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.
