ide/pci/serverworks.c: Fix corruption/timeouts with MegaIDE
It turns out from customer reports to Red Hat and some PCI dumps that the
MegaIDE in RAID mode doesn't provide the drive tuning data that the
serverworks driver expects but sometimes does provide something that
fools the code.
For the RAID class case skip the oem setup and don't trust the BIOS data.
We then tune from scratch and this sorts it out. (This has been confirmed
on an afflicted IBM blade)
[libata serverworks.c never trusts the BIOS in the first place so is
accidentally immune]
