[PATCH] arch: hexagon: kernel: hexagon_ksyms.c remove useless __hexagon_*i3()

[PATCH] arch: hexagon: kernel: hexagon_ksyms.c remove useless __hexagon_*i3()

[Chen Gang]

Only find "DECLARE_EXPORT(__hexagon_*i3)", no related implementations
and callers, so remove them, or will cause ld issue with allmodconfig,
the related error:

    LD      init/built-in.o
  arch/hexagon/kernel/built-in.o:(___ksymtab+__hexagon_umodsi3+0x0): undefined reference to `__hexagon_umodsi3'
  arch/hexagon/kernel/built-in.o:(___ksymtab+__hexagon_udivsi3+0x0): undefined reference to `__hexagon_udivsi3'
  arch/hexagon/kernel/built-in.o:(___ksymtab+__hexagon_modsi3+0x0): undefined reference to `__hexagon_modsi3'
  arch/hexagon/kernel/built-in.o:(___ksymtab+__hexagon_divsi3+0x0): undefined reference to `__hexagon_divsi3'

Oh, sorry, this patch need improved, we can not only remove them simply
(although really no related callers and implementations), I will send
patch v2 later when finish allmodconfig.

Thanks.
