the platform supplies a clkread function that does something other than return 0 (which is the default unless overridden by the platorm code). Supply such a function for the IP22; even if it isn't perfect, it goes a long way to making ntp usable. While I'm at it, move the ticks-per-hz variable out of the struct platform since it's really private to the per-platform interrupt/clock code. XXX: No clkread function supplied for IP32, since it has other problems -- like a hardcoded ticks-per-hz, but the same code as on the IP22 could be used.
