LoongArch: Remove unused arch/loongarch/crypto directory

All LoongArch crypto code was moved to arch/loongarch/lib in
commit 72f51a4f4b ("loongarch/crc32: expose CRC32 functions through
lib"). However, arch/loongarch/crypto still contains stub Kconfig and
Makefile files. Remove these unnecessary files.
