ide-disk: move /proc handling to ide-disk_proc.c (take 3)
While at it: - idedisk_capacity() -> ide_disk_capacity() - idedisk_proc[] -> ide_disk_proc[] - idedisk_settings[] -> ide_disk_settings[] v2/3: Build fix for CONFIG_IDE_PROC_FS=n from Elias Oltmanns. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
