ide: /proc/ide/hd*/settings rework
* 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.
