ide: move IDE settings handling to ide-proc.c
* move __ide_add_setting() ide_add_setting() __ide_remove_setting() auto_remove_settings() ide_find_setting_by_name() ide_read_setting() ide_write_setting() set_xfer_rate() ide_add_generic_settings() ide_register_subdriver() ide_unregister_subdriver() from ide.c to ide-proc.c * set_{io_32bit,pio_mode,using_dma}() cannot be marked static now, fix it * rename ide_[un]register_subdriver() to ide_proc_[un]register_driver(), update device drivers to use new names * add CONFIG_IDE_PROC_FS=n versions of ide_proc_[un]register_driver() and ide_add_generic_settings() * make ide_find_setting_by_name(), ide_{read,write}_setting() and ide_{add,remove}_proc_entries() static * cover IDE settings code in device drivers with CONFIG_IDE_PROC_FS #ifdef, also while at it cover with CONFIG_IDE_PROC_FS #ifdef ide_driver_t.proc * remove bogus comment from ide.h * cover with CONFIG_IDE_PROC_FS #ifdef .proc and .settings in ide_drive_t Besides saner code this patch results in the IDE core smaller by ~2 kB (on x86-32) and IDE disk driver by ~1 kB (ditto) when CONFIG_IDE_PROC_FS=n.
