    * Add struct ide_devset, S_* flags, *DEVSET() & ide*_devset_*() macros.
    * Add 'const struct ide_devset **settings' to ide_driver_t.
    * Use 'const struct ide_devset **settings' in ide_drive_t instead of
      'struct ide_settings_s *settings'.  Then convert core code and device
      drivers to use struct ide_devset and co.:
      - device settings are no longer allocated dynamically for each device
        but instead there is an unique struct ide_devset instance per setting
      - device driver keeps the pointer to the table of pointers to its
        settings in ide_driver_t.settings
      - generic settings are kept in ide_generic_setting[]
      - ide_proc_[un]register_driver(), ide_find_setting_by_name(),
        ide_{read,write}_setting() and proc_ide_{read,write}_settings()
        are updated accordingly
      - ide*_add_settings() are removed
    * Remove no longer used __ide_add_setting(), ide_add_setting(),
      __ide_remove_setting() and auto_remove_settings().
    * Remove no longer used TYPE_*, SETTING_*, ide_procset_t
      and ide_settings_t.
    * ->keep_settings, ->using_dma, ->unmask, ->noflush, ->dsc_overlap,
      ->nice1, ->addressing, ->wcache and ->nowerr ide_drive_t fields
      can now be bitfield flags.
    While at it:
    * Rename ide_find_setting_by_name() to ide_find_setting().
    * Rename write_wcache() to set_wcache().
    There should be no functional changes caused by this patch.
