x86: Fix coreboot config to boot on Chromebook

Browse source 
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.
