ppc/lopec: remove ppc_ide_md hooks
* Add IDE_HFLAG_FORCE_LEGACY_IRQS host flag for Motorola-LoPEC platform to sl82c105 host driver. * Remove ppc_ide_md hooks from arch/ppc/platforms/lopec.c - no need for them (sl82c105 host driver takes care of all this setup). * Then remove no longer needed <linux/ide.h> include. Looking at arch/ppc/configs/lopec_defconfig: ... CONFIG_IDE_GENERIC=y CONFIG_BLK_DEV_IDEPCI=y # CONFIG_IDEPCI_SHARE_IRQ is not set # CONFIG_BLK_DEV_OFFBOARD is not set CONFIG_BLK_DEV_GENERIC=y # CONFIG_BLK_DEV_OPTI621 is not set CONFIG_BLK_DEV_SL82C105=y ... there should be no functional changes unless somebody preferred to disable sl82c105 host driver and use only ide_generic one (but why would anybody want to do such thing :-). PS It seems that lopec_defconfig hasn't been updated for ages but if somebody is going to do it please look into disabling IDE_GENERIC and BLK_DEV_GENERIC config options. Thanks.
