Subject: [PATCH] mx3fb: Fix print format string

%ul was probably meant as %lu since the former would print
an unsigned value and a letter l.

But in fact the whole value we are printing in u32 anyway, so
we don't need the format to be long. Therefore just drop the l
altogether.

Also do we really need 1000UL specification if we
cast to u32 anyway? Or should we drop away the cast instead?
Are pixelclocks over 4GHz possible here?
