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".
