[PATCH] arch: c6x: mm: include "asm/uaccess.h" to pass compiling

[Chen Gang]

Need include "asm/uaccess.h" to pass compiling.

The related error (with allmodconfig):
  arch/c6x/mm/init.c: In function ‘paging_init’:
  arch/c6x/mm/init.c:46:2: error: implicit declaration of function ‘set_fs’ [-Werror=implicit-function-declaration]
  arch/c6x/mm/init.c:46:9: error: ‘KERNEL_DS’ undeclared (first use in this function)
  arch/c6x/mm/init.c:46:9: note: each undeclared identifier is reported only once for each function it appears in
