frv: hide uncached_access() when pgprot_noncached is not #defined 

Hide uncached_access() when pgprot_noncached is not #defined.  This prevents
the following warning:

	  CC      drivers/char/mem.o
	drivers/char/mem.c:229: warning: 'uncached_access' defined but not used

Repairs d7d4d849b4 ("drivers/char/mem.c:
cleanups").
