ARM: footbridge: convert to clockevents/clocksource

Browse source

The Footbridge platforms have some reasonable timers in the host bridge,
which we use for most footbridge-based platforms.  However, NetWinder's
clock these using a spread-spectrum clock which makes them too unstable
for time keeping.  So we have to rely on the PIT.

Convert both Footbridge timers and PIT timers to use the clocksource
and clockevent infrastructure.  Tested on Netwinder.
