Subject: [PATCH -next] alpha: Define ioremap_uc and ioremap_wc

Commit 3cc2dac5be3f ("drivers/video/fbdev/atyfb: Replace MTRR UC hole
with strong UC") introduces calls to ioremap_wc and ioremap_uc. This
causes build failures with alpha:allmodconfig. Map the missing functions
to ioremap_nocache.

        Replace MTRR UC hole with strong UC")
