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 parisc:allmodconfig. Map the missing
functions to ioremap_nocache.
Fixes: 3cc2dac5be3f ("drivers/video/fbdev/atyfb:
Replace MTRR UC hole with strong UC")
