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.

	  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.
