h8300 does not implement ioremap_wc(), but implement ioremap(), need
define ioremap_wc() just like "asm-generic/io.h" to pass compiling.
The related error (allmodconfig for h8300):
drivers/video/uvesafb.c: In function 'uvesafb_ioremap':
drivers/video/uvesafb.c:1563:2: error: implicit declaration of function 'ioremap_wc' [-Werror=implicit-function-declaration]
