Need generic ioremap_wc(), or can not pass compiling with allmodconfig,
the related error:
CC [M] drivers/gpu/drm/drm_bufs.o
drivers/gpu/drm/drm_bufs.c: In function 'drm_addmap_core':
drivers/gpu/drm/drm_bufs.c:217: error: implicit declaration of function 'ioremap_wc'
drivers/gpu/drm/drm_bufs.c:218: warning: assignment makes pointer from integer without a cast
