Ugh. This is hard to read, and it will get much worse if we then end
up making the conditional more complicated if we actually want to
introduce some page size logic..

How about we do a

  config DISABLE_NTFS_RW
        bool
        default y if PPC

and then in NTFS_RW we just do

        depends on !DISABLE_NTFS_RW

which at least makes each case easy, and makes it much clearer if we
extend that DISABLE_NTFS_RW condition later.
