ATA panic PR (update)

[Alex K]

Hello, everyone!

Seems like problem is with incorrect detection ATA of controller.

5.2.1-release:
atapci0: <SiS 5513 UDMA33 controller> port 0x1100-0x110f at device 2.5 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata0: [MPSAFE]

5.2-current:
atapci0: <SiS 961 UDMA100 controller> port
 0x110b-0x111a,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 2.5 on pci0
ata0: at 0x1f0 irq 14 on atapci0

Cheers,
           AL.
