Subject: [PATCH 07/11] ppc/sandpoint: remove ppc_ide_md hooks
* Add IDE_HFLAG_FORCE_LEGACY_IRQS host flag for Motorola-Sandpoint platform
to sl82c105 host driver.
* Disable ide_generic host driver in arch/ppc/configs/sandpoint_defconfig
and enable sl82c105 one.
* Remove ppc_ide_md hooks from arch/ppc/platforms/sandpoint.c - no need for
them (sl82c105 host driver takes care of all this setup).
* Then remove no longer needed <linux/ide.h> include.
* Also update arch/ppc/platforms/sandpoint.h.
Unfortunately (unlike lopec's case) sl82c105 host driver was not enabled
in defconfing so there is a funcionality change.
[ Not a big deal since sl82c105 is superior over ide_generic. ]
