Tiezhu Yang 048cc2378c MIPS: SGI-IP22: Remove unnecessary check of GCC option
According to Documentation/process/changes.rst, the minimal version of GCC
is 5.1, and -mr10k-cache-barrier=store is supported with GCC 5.1 [1], just
remove the unnecessary check to fix the build error [2]:

  arch/mips/sgi-ip22/Platform:28: *** gcc doesn't support needed option -mr10k-cache-barrier=store.  Stop.
