[U-Boot] [PATCH] x86: Fix coreboot config to boot on Chromebook

[Simon Glass]

The config is current broken. It compiles but does not boot because IDE is
enabled. Remove all IDE options, and enable SCSI instead.

Also add a working boot command and Linux bootargs, and enable command
line editing to make it easier to work with.
