sh: add EXPORT_SYMBOL(min_low_pfn) and EXPORT_SYMBOL(max_low_pfn) to sh_ksyms_32.c 



Min_low_pfn and max_low_pfn were used in pfn_valid macro if defined
CONFIG_FLATMEM.  When the functions that use the pfn_valid is used in
driver module, max_low_pfn and min_low_pfn is to undefined, and fail to
build.

  ERROR: "min_low_pfn" [drivers/block/aoe/aoe.ko] undefined!
  ERROR: "max_low_pfn" [drivers/block/aoe/aoe.ko] undefined!
  make[2]: *** [__modpost] Error 1
  make[1]: *** [modules] Error 2

This patch fix this problem.
