[ARM] 3727/1: fix ucb initialization on collie

Patch from Pavel Machek

From: Dirk Opfer <Dirk@Opfer-Online.de>

Fix ucb initialization on collie. Wrong frequency was used and that
led to things not working quite correctly. (I had to actually disable
checks in my tree to get it to boot). It now includes all the
neccessary parts to get it to compile :-).
