ide: make /proc/ide/ optional
All important information/features should be already available through sysfs and ioctl interfaces. Add CONFIG_IDE_PROC_FS (CONFIG_SCSI_PROC_FS rip-off) config option, disabling it makes IDE driver ~5 kB smaller (on x86-32). While at it add CONFIG_PROC_FS=n versions of proc_ide_{create,destroy}() and remove no longer needed #ifdefs. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
