rafal 1a9f819d84 Make microtime(9) do interpolation to get better-than-hz resolution, if
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.
