Use dax_is_supported() to validate whether the architecture has virtually aliased data caches at mount time. Silently disable DAX if dax=always is requested as a mount option on an architecture which does not support DAX. This is relevant for architectures which require a dynamic check to validate whether they have virtually aliased data caches.
