OMAP1/2/3 clock: remove paranoid checks in preparation for clock{,2xxx,3xxx}_data.c
Some parts of the clock code took advantage of the fact that the statically allocated clock tree was in clock{,24xx,34xx}.c's local namespace to do some extra argument checks. These are overzealous and are more difficult to maintain when the clock tree is in a separate namespace, so, remove them. Signed-off-by: Paul Walmsley <paul@pwsan.com>
