Subject: [PATCH 2/4] video/logo: fix unneeded generation of font C files

Currently, all the font C files are generated irrespective of CONFIG
options. Adding them to extra-y is wrong. What we need to do here is
to add them to 'targets' so that if_changed works properly.

All files listed in 'targets' are cleaned, so clean-files is unneeded.
