[U-Boot] CONFIG_HZ = 1000 makes timer stop working on SA1100

[Kristoffer Ericson]

Hi,

Subject pretty much says it all. When using CONFIG_HZ = 1000, it can no longer
handle any delays (ex. autoboot = 10s goes directly to bootup). Moving it back
to the correct HZ setting for SA1100 makes it work properly again.
So either its due to the problem Jochen pointed out earlier or simply that
SA1100 timer driver isnt adjusted for it. Just wanted people to know
before I start digging.

Best wishes
