I don't remember why I mentioned to asn1_decoder.c here, but
When this statement is removed from kernel.h, some files cannot
be compiled.
The fact is that sprintf() is used in time.h without including any
related headers.
(There are still bunch of *missing headers* issues in U-Boot.)

I will add one more patch against time.h here.
