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.

kbuild: sync top Makefile with Linux 3.18-rc1

Since Linux 3.15, relative path feature and related fixes,
cleanups have been merged to the top Makefile.

The relative path feature looks stable enough, so let's import it
to U-Boot along with various cleanups.

kconfig: add sanity checks for SPL configuration

For the SPL configuration, "make <dir>/<target>" is used.
Here,
<dir> is either "spl" or "tpl"
<target> is one of "config", "menuconfig", "xconfig", etc.

This commit adds two checks:

[1] If <dir> is given an unsupported subimage, the configuration
should error out like this:

$ make qpl/menuconfig
***
*** "make qpl/menuconfig" is not supported.
***

[2] Make sure that "CONFIG_SPL" is enabled in the ".config" before
running "make spl/menuconfig. Otherwise, the SPL image
is not built at all. Having "spl/.config" makes no sense.
In such a case, the configuration should exit with a message:

$ make spl/menuconfig
***
*** Create ".config" with "CONFIG_SPL" enabled
*** before "make spl/menuconfig".
