Please be careful with 'else' in SPL. It can pull in code that we
don't need. I think the second else here should be 'if
prodid_is_exynos5250()' or something like that. Otherwise we can find
ourselves including the tables for both 5250 and 5420 in the SPL for
5420. Granted we might want our SPL to support both, but if the CONFIG
options are not set for both, then the user does not want both, so we
should avoid waiting the code space.

Simon
