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").
