Subject: [PATCH] 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'
