vboot_api_kernel: Print warning in TONORM when GBB flags force DEV.

Browse Source 
We use gbb-flag-force-dev-switch-on in default firmware images to make
things easier for factory and some devs.

But when we request normal mode there should be some sort of warning/error
telling the user that this is not available, otherwise we can spent time trying
to figure out why the firmware doesn't work.

BRANCH=all
BUG=chrome-os-partner:14474
TEST=flash image to Link, set GBB flags to 0x39, boot to DEV screen
     and press SPACE (TONORM); gets beep and warning messages.
