ide: move IDE settings handling to ide-proc.c

Browse source 
* 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.
