kconfig: sync kconfig files with Linux 3.18-rc1
This commit imports Kconfig updates from Linux 3.18-rc1.
'kvmconfig' and 'tinyconfig' help message have been commented out
since they are unavailable at least now; in the future perhaps
we can implement 'tinyconfig' to disable most of CONFIG_CMD_* to
create a very small U-Boot image.
