New CONFIG options should be added via Kconfig. To help prevent new ad-hoc CONFIGs from being added, give a build error when these are detected.

I worried about the increased build time due to find/grep on all Kconfig files, but at least with a hot disk cache it seems to make no noticeable difference:-)
FWIW, CONFIG_SPL_GPIO_SUPPORT is missing in the whitelist, which affects the Jetson TK1 build (and likely all/most other Tegra boards).
Ah, that's why "CONFIG_" is in the current whitelist; there are Makefiles that reference CONFIG_$(SPL)_SOMETHING. Handling that automatically might be a little involved for a one-off thing; I guess you'd need to manually fix up the whitelist for this?
