There are two places in the cfb_console driver that test whether CONFIG_VGA_AS_SINGLE_DEVICE is defined or not, but actually it is unnecessary, hence clean it up.

This is needed by some boards, e.g. (just a sample):

Sorry, I failed to check this CONFIG_VGA_AS_SINGLE_DEVICE is actually defined by so many boards. But I still see the logic is not straight forward, due to the variable 'have_keyboard' is equal to '!defined(CONFIG_VGA_AS_SINGLE_DEVICE)'. Can we do it like this:
Well the presence of a keyboard is also controlled by device tree. If this moved to Kconfig then we could use if() instead of #ifdef which would be better.

I believe this is broken?
i don't have this board but it does seem to build OK and these functions are in the image. What is broken?
