drivers/video/fbdev: use ioremap_wc/wt() instead of __ioremap()
_PAGE_NO_CACHE is a platform specific flag. In addition, this flag
is misleading because one would think it requests a noncached page
whereas a noncached page is _PAGE_NO_CACHE | _PAGE_GUARDED
_PAGE_NO_CACHE alone means write combined noncached page, so lets
use ioremap_wc() instead.
_PAGE_WRITETHRU is also platform specific flag. Use ioremap_wt()
instead.
