Sudip Mukherjee e928f35061 blackfin: define dummy pgprot_writecombine for !MMU
blackfin allmodconfig build fails with the error:

  ../sound/core/pcm_native.c: In function 'snd_pcm_lib_default_mmap':
  ../sound/core/pcm_native.c:3386:24: error: implicit declaration of function 'pgprot_writecombine' [-Werror=implicit-function-declaration]
     area->vm_page_prot = pgprot_writecombine(area->vm_page_prot);
                          ^
  ../sound/core/pcm_native.c:3386:22: error: incompatible types when assigning to type 'pgprot_t {aka struct <anonymous>}' from type 'int'
     area->vm_page_prot = pgprot_writecombine(area->vm_page_prot);
                        ^

When !MMU, asm-generic will not define default pgprot_writecombine, so
blackfin needs to define it by itself.

The patch idea is from commit 65b9ab888c ("arch/c6x/include/asm/pgtable.h:
define dummy pgprot_writecombine for !MMU")
