ide: drop 'timeout' and 'expiry' arguments from ide_pc_intr()
* Move idescsi_expiry() to ide-atapi.c. * Move get_timeout() to <linux/ide.h>. * Drop 'timeout' and 'expiry' arguments from ide_pc_intr(). While at it: * idescsi_expiry() -> ide_scsi_expiry() * get_timeout() -> ide_scsi_get_timeout() There should be no functional changes caused by this patch.
