  LoongArch: Update Loongson-3 default config file (2023-09-07 12:06:20 +0800)

----------------------------------------------------------------
LoongArch changes for v6.6

1, Allow usage of LSX/LASX in the kernel;
2, Add SIMD-optimized RAID5/RAID6 routines;
3, Add Loongson Binary Translation (LBT) extension support;
4, Add basic KGDB & KDB support;
5, Add building with kcov coverage;
6, Add KFENCE (Kernel Electric-Fence) support;
7, Add KASAN (Kernel Address Sanitizer) support;
8, Some bug fixes and other small changes;
9, Update the default config file.

Note: There is a conflicts in arch/loongarch/mm/pgtable.c but can be
simply fixed by adjusting context.
