PATCH: IDE - do spin up for all platforms

This was put in for PPC specifically and defined in the 2.4 tree to be paranoid about breaking stuff. The actual wait for hwif spin up is however perfectly correct for all drives. In the normal PC case the PC BIOS has done this but with other embedded boxes and with things like LinuxBIOS it may not have done. Thus it should always be done.
