PATCH 1/1 arch: unicore32: kernel: ksyms: remove 'bswapsi2' and 'muldi3' to avoid compiling failure

After check the code, 'bswapsi2' and 'muldi3' are useless for unicore32, so can remove them to avoid compiling failure.

The related error (with allmodconfig under unicore32):

LD init/built-in.o
arch/unicore32/kernel/built-in.o:(___ksymtab+__muldi3+0x0): undefined reference to __muldi3' arch/unicore32/kernel/built-in.o:(___ksymtab+__bswapsi2+0x0): undefined reference to __bswapsi2'

Thanks.

For __muldi3, it is no longer used by gcc, so I think that's ok. For __bswapsi2, maybe it's because I copied it from arm.
