block: remove BLK_DEV_DAX config option
The functionality for block device DAX was already removed with commit
acc93d30d7d4 ("Revert "block: enable dax for raw block devices"")
However, we still had a config option hanging around that was always
disabled because it depended on CONFIG_BROKEN. This config option was
introduced in commit 03cdadb04077 ("block: disable block device DAX by
default")
This change reverts that commit, removing the dead config option.
