Log Message:
Significant cleanup and bug fix of root device detection:
* On systems where it's relevant (6600, kn300, kn8ae), check which PCI bus
  hierarchy we're looking at.
* Consistently check PCI function numbers (important for quad-channel ATA
  controllers).
* Check the channel number (important for ATA and multi-channel SCSI
  controllers).
* Check logical unit numbers.
* Use strcasecmp() to check b->protocol; the case is different depending on
  the firmware revision.
* Remove b->boot_dev_type check; it's unneeded.
* Remove extraneous unneeded variables.

Not only does this fix a few PRs and multiple long-standing bugs, but the
code is smaller too.
