x86: Kconfig: Divide the target selection to vendor/model
Let arch/x86/Kconfig prompt board vendor first, then select
the board model under that vendor. This way arch/x86/Kconfig
only needs concern board vendor and leave the supported target
list to board/<vendor>/Kconfig.

+ This target is used for running U-Boot on top of coreboot. In
+ this case coreboot does the early inititalisation, and U-Boot
+ takes over once the RAM, video and CPU are fully running.
+ U-Boot is loaded as a fallback payload from coreboot, in
+ coreboot terminology. This method was used for the Chromebook
+ Pixel when launched.
