[PATCH 09/12] ARM: netx: Remove LATCH and CLOCK_TICK_RATE dependency

As part of work to remove the global CLOCK_TICK_RATE symbol,
this patch defines a sub-arch local value for use by the
netx code. Once all LATCH and CLOCK_TICK_RATE references
are removed, we will remove all the definitions across
sub-arches.
