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.

If you are unsure, say N here.
config IDE_PROC_FS
bool "legacy /proc/ide/ support"
depends on IDE && PROC_FS
default y
help
This option enables support for the various files in
/proc/ide. In Linux 2.6 this has been superseded by
files in sysfs but many legacy applications rely on this.
If unsure say Y.
