logo: move declarations of logos to linux_logo.h
there was a mismatch between externs in logo.c and code generated by pnmtologo
(on old tree, you need to rm drivers/video/logo/logo_*.c before compilation)
This patch (after I fixed it) keeps on causing trouble: mismatches between
the header file declarations and the actual definitions of the lookup
tables. This happens as I apply and unapply the patch.
It _shouldn't_ happen, but there would appear to be some missing makefile
rules. I guess the C files aren't being regenerated when
scripts/pnmtologo.c has been altered, so the C files aren't matching the
header which this patch alters.
