ide: generic IDE PCI driver, add another device exception 

generic IDE PCI driver, add another device exception

This device is char device and is grabbed by generic ide driver:
00:0b.0 Class ffff: National Semiconductor Corporation 87410 IDE (rev ff) (prog-if ff)
	Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-

Disallow generic IDE PCI driver to grab it by adding next condition. Also
consolidate exceptions to one bigger 'switch (dev->vendor)'.
