[U-Boot] [PATCH] x86: Fix IDE configuration for the coreboot board

[Gabe Black]

The ports for the IDE controller were reversed. Because u-boot was
configured to look for at most one bus with one disk attached, it looked at
the wrong one, didn't find anything, and quit looking.

This change does not increase the number of busses or devices per bus that
u-boot should check for because scanning for them adds a noticable pause
during boot. It does, however, correct some comments describing the limits.
